Mol-ecular structure of fac-[Mo(CO)₃(DMSO)₃].

ABSTRACT: The title compound, tri-carbonyl-tris-(dimethyl sulfoxide)-molybdenum, [Mo(C₂H₆OS)₃(CO)₃] or fac-[Mo(CO)₃(DMSO)₃], crystallizes in the triclinic space group P with two mol-ecules in the unit cell. The geometry around the central molybdenum is slightly distorted octa-hedral and the facial isomer is found exclusively. The packing within the crystal is stabilized by three-dimensional non-classical inter-molecular hydrogen-bonding contacts between individual methyl substituents of di-methyl sulfoxide and the oxygen atoms of either another di-methyl sulfoxide or a carbonyl ligand on adjacent complex mol-ecules. The observed bond lengths in the carbonyl ligands and between carbonyl carbon atoms and molybdenum are correlated to the observed FT-IR bands for the carbonyl stretches and compared to respective metrical parameters of related complexes.

Crystal and mol-ecular structure of aflatrem.

Project description:The crystal structure of the title compound, C32H39NO4, confirms the absolute configuration of the seven chiral centres in the mol-ecule. The molecule has a 1,1-dimethylprop-2-enyl substituent on the indole nucleus and this nucleus shares one edge with the five-membered ring which is, in turn, connected to a sequence of three edge-shared fused rings. The skeleton is completed by the 7,7-trimethyl-6,8-dioxabi-cyclo-[3.2.1]oct-3-en-2-one group connected to the terminal cyclohexene ring. The two cyclohexane rings adopt chair and half-chair conformations, while in the dioxabi-cyclo-[3.2.1]oct-3-en-2-one unit, the six-membered ring has a half-chair conformation. The indole system of the mol-ecule exhibits a tilt of 2.02 (1)° between its two rings. In the crystal, O-H⋯O hydrogen bonds connect mol-ecules into chains along [010]. Weak N-H⋯π inter-actions connect these chains, forming sheets parallel to (10-1).

Mol-ecular structure, DFT studies and Hirshfeld analysis of anthracenyl chalcone derivatives.

Project description:The mol-ecular and crystal structure of two new chalcone derivatives, (E)-1-(anthracen-9-yl)-3-[4-(piperidin-1-yl)phen-yl]prop-2-en-1-one, C28H25NO, (I), and (E)-1-(anthracen-9-yl)-3-[4-(di-phenyl-amino)-phen-yl]prop-2-en-1-one, C35H25NO, (II), with the fused-ring system at the same position are described. In the crystals of (I) and (II), the mol-ecules are linked via C-H⋯O hydrogen bonds into inversion dimers, forming R22(22) and R22(14) ring motifs, respectively. Weak inter-molecular C-H⋯π inter-actions further help to stabilize the crystal structure, forming a two-dimensional architecture. The mol-ecular structures are optimized using density functional theory (DFT) at B3LYP/6-311 G++(d,p) level and compared with the experimental results. The smallest HOMO-LUMO energy gaps of (I) (exp . 2.76 eV and DFT 3.40 eV) and (II) (exp . 2.70 eV and DFT 3.28 eV) indicates the suitability of these crystals in optoelectronic applications. All inter-molecular contacts and weaker contributions involved in the supra-molecular stabilization are investigated using Hirshfeld surface analysis. The mol-ecular electrostatic potential (MEP) further identifies the positive, negative and neutral electrostatic potential regions of the mol-ecules.

Mol-ecular structure of tris-[(6-bromo-pyridin-2-yl)meth-yl]amine.

Project description:Coordination compounds of polydentate nitro-gen ligands with metals are used extensively in research areas such as catalysis, and as models of complex active sites of enzymes in bioinorganic chemistry. Tris(2-pyridyl-meth-yl)amine (TPA) is a tripodal tetra-dentate ligand that is known to form coordination compounds with metals, including copper, iron and zinc. The related compound, tris-[(6-bromo-pyridin-2-yl)meth-yl]amine (TPABr3), C18H15Br3N4, which possesses a bromine atom on the 6-position of each of the three pyridyl moieties, is also known but has not been heavily investigated. The mol-ecular structure of TPABr3 as determined by X-ray diffraction is reported here. The TPABr3 molecule belongs to the triclinic, P space group and displays interesting intermolecular Br⋯Br interactions that provide a stabilizing influence within the molecule.

Mol-ecular and crystal structure of gossypol tetra-methyl ether with an unknown solvate.

Project description:The title compound, C34H38O8 (systematic name: 5,5'-diisopropyl-2,2',3,3'-tetra-meth-oxy-7,7'-dimethyl-2H,2'H-8,8'-bi-[naphtho-[1,8-bc]furan]-4,4'-diol), has been obtained from a gossypol solution in a mixture of dimethyl sulfate and methanol. The mol-ecule is situated on a twofold rotation axis, so the asymmetric unit contains one half-mol-ecule. In the mol-ecule, the hy-droxy groups are involved in intra-molecular O-H⋯O hydrogen bonds, and the two naphthyl fragments are inclined each to other by 83.8 (1)°. In the crystal, weak C-H⋯O and C-H⋯π inter-actions consolidate the packing, which exhibits channels with an approximate diameter of 6 Å extending along the c-axis direction. These channels are filled with highly disordered solvent mol-ecules, so their estimated scattering contribution was subtracted from the observed diffraction data using the SQUEEZE option in PLATON [Spek, A. L. (2015). Acta Cryst. C71, 9-18].

Calixarene-based mol-ecular capsule from olefin metathesis.

Project description:The reaction of tetra-kis-(all-yloxy)calix[4]arene with the first-generation Grubbs catalyst, followed by catalytic hydrogenation, gave the novel bis-calixarene 15,20,46,51,64,69,74,79-octa-oxatridecacyclo[32.28.8.8(3,28).1(13,53).1(22,44).0(9,14).0(21,26).0(38,70).0(40,45).0(52,57).0(59,63).0(7,80).0(32,73)]octa-conta-1(63),3,5,7(80),9(14),10,12,21,23,25,28(73),29,31,34,36,38(70),40,42,44,52,54,56,59,61-tetra-cosa-ene benzene monosolvate, C72H72O8·C6H6. The structure consists of two calix[4]arene units connected by four-carbon chains at each of the four O atoms on their narrow rims, to form a cage. Each of the calix[4]arene units has a flattened cone conformation in which two of the opposite aryl groups are closer together and nearly parallel [dihedral angle between planes = 7.35 (16)°], and the other two aryl groups are splayed outward [dihedral angle between planes = 72.20 (8)°]. While the cavity contains no solvent or other guest mol-ecule, there is benzene solvent mol-ecule in the lattice. Two of the alkyl linking arms were disordered over two conformations with occupancies of 0.582 (3)/0.418 (3) and 0.33 (4)/0.467 (4). They were constrained to have similar metrical and thermal parameters.

Crystal structure, Hirshfeld surface analysis, DFT optimized mol-ecular structure and the mol-ecular docking studies of 1-[2-(cyano-sulfan-yl)acet-yl]-3-methyl-2,6-bis-(4-methyl-phen-yl)piperidin-4-one.

Project description:The two mol-ecules in the asymmetric unit of the title compound, C23H24N2O2S, have a structural overlap with an r.m.s. deviation of 0.82 Å. The piperidine rings adopt a distorted boat conformation. Intra- and inter-molecular C-H⋯O hydrogen bonds are responsible for the cohesion of the crystal packing. The inter-molecular inter-actions were qu-anti-fied and analysed using Hirshfeld surface analysis. The mol-ecular structure optimized by density functional theory (DFT) at the B3LYP/6-311++G(d,p)level is compared with the experimentally determined mol-ecular structure in the solid state.

Fluorenonophane chloro-benzene solvate: mol-ecular and crystal structures.

Project description:The title compound, 19 H,79 H-3,5,9,11-tetra-oxa-1,7(2,7)-difluorena-4,10(1,3)-dibenzena-cyclo-dodeca-phane-19,79-dione (fluorenonophane), exists as a solvate with chloro-benzene, C42H28O6·C6H5Cl. The fluorenonophane contains two fluorenone fragments linked by two m-substituted benzene fragments. Some decrease in its macrocyclic cavity leads to a stacking inter-action between the tricyclic fluorenone fragments. In the crystal, the fluorenonophane and chloro-benzene mol-ecules are linked by weak C-H⋯π(ring) inter-actions and C-H⋯Cl hydrogen bonds. The Cl atom of chloro-benzene does not form a halogen bond. A Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter-molecular contacts found in the crystal structure.

Crystal and mol-ecular structure of 4-fluoro-1H-pyrazole at 150 K.

Project description:Only two 4-halo-1H-pyrazole crystal structures are known to date (chloro and bromo, the structure of 4-iodo-1H-pyrazole has not been reported yet). The triclinic structure of 4-fluoro-1H-pyrazole, C3H3FN2 (P ), reported here is not isomorphous with those of the chloro and bromo analogues (which are isomorphous, ortho-rhom-bic Pnma). To avoid sublimation during the measurement, diffraction data were collected at 150 K. Two crystallographically unique 4-fluoro-1H-pyrazole moieties linked by an N-H⋯N hydrogen bond are found in the asymmetric unit. Unlike the trimeric supra-molecular motifs found in the structures of the chloro and bromo analogues, 4-fluoro-1H-pyrazole forms one-dimensional chains by inter-molecular hydrogen bonding in the crystal.

Crystal and mol-ecular structure of 2-methyl-1,4-phenyl-ene bis-(3,5-di-bromo-benzoate).

Project description:The aryl diester compound, 2-methyl-1,4-phenyl-ene bis-(3,5-di-bromo-benzoate), C21H12Br4O4, was synthesized by esterification of methyl hydro-quinone with 3,5-di-bromo-benzoic acid. A crystalline sample was obtained by cooling a sample of the melt (m.p. = 502 K/DSC) to room temperature. The mol-ecular structure consists of a central benzene ring with anti-3,5-di-bromo-benzoate groups symmetrically attached at the 1 and 4 positions and a methyl group attached at the 2 position of the central ring. In the crystal structure (space group P), mol-ecules of the title aryl diester are located on inversion centers imposing disorder of the methyl group and H atom across the central benzene ring. The crystal structure is consolidated by a network of C-H⋯Br hydrogen bonds in addition to weaker and offset π-π inter-actions involving the central benzene rings as well as the rings of the attached 3,5-di-bromo-benzoate groups.

Crystal structure of a new mol-ecular salt: 4-amino-benzenaminium 5-carb-oxy-penta-noate.

Project description:The asymmetric unit of the title mol-ecular salt (systematic name: 4-amino-anilinium 5-carb-oxy-penta-noate), C6H9N2+·C6H9O4-, consists of half a 4-amino-benzenaminium cation (4-ABA) and half a 5-carb-oxy-penta-noate anion (5-CP); the other half of each ion is generated by inversion symmetry. Protonation of p-phenyl-enedi-amine (PPDA) leads to the formation of a 1:1 salt, but scrutiny of the crystal structure reveals that both of the amine groups of PPDA are partially protonated, with a half-occupied H atom. For the 5-CP anion, an H atom is positioned on an inversion center midway between two O atoms of inversion-related 5-CP ions. In the crystal, the 5-CP anions are linked by the O-H⋯O hydrogen bond to form chains propagating along the [1-10] direction. The chains are linked via N-H⋯O and N-H⋯N hydrogen bonds involving the 4-ABA cations, forming a three-dimensional supra-molecular framework. The title salt was also prepared by mechanochemical synthesis using liquid-assisted grinding (LAG). Its PXRD pattern matches that of the simulated pattern of the crystal structure of the title mol-ecular salt.
