Crystal structure of {N-[(6-bromo-pyridin-2-yl)(phen-yl)methyl-idene]-2,6-di-methyl-aniline-κ2N,N'}di-chlorido-zinc di-chloro-methane hemisolvate.

Project description:The solvated title compound, [ZnCl2(C20H17BrN2)]·0.5CH2Cl2, comprises a bidentate imino-pyridine ligand and two Cl atoms bound to a zinc2+ cation in a distorted tetra-hedral arrangement. The chelate bond lengths are consistent with localized C=N double bonds and a C-C single bond, as expected for an unreduced ligand bound to a closed-shell transition metal cation. Apart from weak nonclassical C-H⋯Cl hydrogen bonds between the complex mol-ecules and the disordered solvent mol-ecules (occupancy = 0.5), no further significant inter-molecular inter-actions are observed.

Penta-aqua-(di-methyl-formamide)-cobalt(II) sulfate di-methyl-formamide monosolvate.

Project description:The title compound, [Co(C3H7NO)(H2O)5]SO4·C3H7NO, contains five aqua ligands, a Co(II) atom, a sulfate ion and both a coordinating and a non-coordinating di-methyl-formamide (DMF) mol-ecule. The DMF solvent mol-ecule lies between the complex units, which are located along the b axis. The sulfate ion is for charge balance. The Co(II) atom has distorted octa-hedral coordination geometry, being ligated by five aqua ligands and the O atom of the DMF ligand. O-H?O hydrogen bonds between the aqua ligands and the sulfate anion and non-coordinating DMF molecule lead to the formation of a three-dimensional network. Since all constituents lie on a mirror plane, the H atoms of all methyl groups and of one of the aqua ligands are equally disordered over two positions.

Crystal structure, Hirshfeld surface analysis and DFT studies of tetra-kis-(μ-3-nitro-benzoato-κ2 O 1:O 1')bis-[(N,N-di-methyl-formamide-κO)copper(II)] di-methyl-formamide disolvate.

Project description:The title compound, [Cu2(C7H4NO4)4(C3H7NO)2]·(C3H7NO)2, is a binuclear copper(II) complex located on an inversion center midway between the two copper(II) cations. The asymmetric unit consists of one CuII cation, two 3-nitro-benzoato ligands, and two di-methyl-formamide (DMF) mol-ecules, one of which coordinates to the CuII cation and one is a solvate mol-ecule. The carboxyl-ate groups of the ligands bridge two CuII cations with a Cu-Cu distance of 2.6554 (6) Å, completing a distorted octa-hedral O5Cu coordination environment. The dihedral angles between the carboxyl-ate and the aromatic ring planes of the two independent ligands are different from one another, viz. 5.2 (3) and 23.9 (3)°. The three-dimensional structure is consolidated by weak C-H⋯O inter-actions and stabilized by π-π stacking inter-actions between the aromatic rings. The complex and the free ligand were further characterized by Fourier-transform infrared spectroscopy (FT-IR), and the energies of the frontier mol-ecular orbitals of the complex were determined by DFT calculations at the B3LYP/def2-TZVP level of theory.

2,2'-(Disulfanedi-yl)di-benzoic acid N,N-di-methyl-formamide monosolvate: crystal structure, Hirshfeld surface analysis and computational study.

Project description:The title 1:1 solvate, C14H10O4S2·C3H7NO, features a twisted mol-ecule of 2,2'-di-thiodi-benzoic acid (DTBA), with the central C-S-S-C torsion angle being -88.57?(6)°, and a mol-ecule of di-methyl-formamide (DMF). The carb-oxy-lic acid groups are, respectively, close to co-planar and twisted with respect to the benzene rings to which they are connected as seen in the CO2/C6 torsion angles of 1.03?(19) and 7.4?(2)°. Intra-molecular, hypervalent S?O inter-actions are noted [S?O = 2.6140?(9) and 2.6827?(9)?Å]. In the crystal, four-mol-ecule aggregates are formed via DTBA-O-H?O(DMF) and DTBA-O-H?O(DTBA) hydrogen bonding, the latter via an eight-membered {?OHCO}2 homosynthon. These are linked into supra-molecular layers parallel to (011) via benzene-C-H?O(DTBA) and DTBA-C=O??(benzene) inter-actions, with the connections between these, giving rise to a three-dimensional architecture, being of the type benzene-C-H??(benzene). An analysis of the calculated Hirshfeld surfaces indicates, in addition to the aforementioned inter-molecular contacts, the presence of stabilizing inter-actions between a benzene ring and a quasi-?-system defined by O-H?O hydrogen bonds between a DTBA dimer, i.e. the eight-membered {?OCOH}2 ring system, and between a benzene ring and a quasi-?(OCOH?OCH) system arising from the DTBA-O-H?O(DMF) hydrogen bond. The inter-centroid separations are 3.65 and 3.49?Å, respectively.

Crystal structure of catena-poly[[[aqua-bis-(di-methyl-formamide-?O)magnesium(II)]-?3-(2,2'-bi-pyridine-5,5'-di-carboxyl-ato-?5O2:O2':N,N':O5)-[di-chlorido-platinum(II)]] di-methyl-formamide monosolvate].

Project description:The title compound, {[MgPtCl2(C12H6N2O4)(C3H7NO)2(H2O)]·C3H7NO} n , is a one-dimensional coordination polymer. The structure consists of Pt-functionalized bi-pyridine ligands connected by MgII cations, as well as coordinating and non-coordinating solvent mol-ecules. The PtII cation is coordinated by the two N atoms of the bi-pyridine moiety and two Cl atoms in a square-planar fashion. This coordination induces an in-plane bend along the bi-pyridine backbone of approximately 10° from the linear ideal of a conjugated ?-system. Likewise, the coordination to the MgII cation induces a significant bowing of the plane of the bi-pyridine of about 12°, giving it a distinct curved appearance. The carboxyl-ate groups of the bi-pyridine ligand exhibit moderate rotations relative to their parent pyridine rings. The MgII cation has a fairly regular octa-hedral coordination polyhedron, in which three vertices are occupied by O atoms from the carboxyl-ate groups of three different bi-pyridine ligands. The remaining three vertices are occupied by the O atoms of two di-methyl-formamide (DMF) mol-ecules and one water mol-ecule. The one-dimensional chains are oriented in the [01-1] direction, and non-coordinating DMF mol-ecules can be found in the space between the chains. The shortest inter-molecular O?H contacts are 2.844?(4) and 2.659?(4)?Å, suggesting moderate hydrogen-bonding inter-actions. In addition, there is a short inter-molecular Pt?Pt contact of 3.491?(1)?Å, indicating a Pt stacking inter-action. Some structure-directing contribution from the hydrogen bonding and Pt?Pt inter-action is probable. However, the crystal packing seems to be directed primarily by van der Waals inter-actions.

Poly[[?-(3-amino-pyridine)-?(2)N:N'-?-chlorido-chlorido(N,N'-dimethyl-formamide-?O)nickel(II)] N,N'-dimethyl-formamide monosolvate].

Project description:The title compound, {[NiCl(2)(C(5)H(6)N(2))(C(3)H(7)NO)]·C(3)H(7)NO}(n), is a two-dimensional polymer in which the Ni(II) atom is coordinated by two N atoms from two 3-amino-pyridine ligands, one O atom from a dimethyl-formamide (DMF) group, one terminal Cl and two bridging Cl atoms in a distorted octa-hedral geometry. The Ni(II) atoms are bridged by the 3-amino-pyridine ligands [Ni?N = 6.7048?(3)?Å] and Cl(-) atoms [Ni?N = 3.5698?(3)?Å], forming (4,4) two-dimensional nets. The DMF solvent mol-ecule and the non-bridged Cl(-) ions participate in N-H?O and N-H?Cl hydrogen bonds with the amino groups.

Crystal structure and Hirshfeld surface analysis of 4-{[(anthracen-9-yl)meth-yl]amino}-benzoic acid di-methyl-formamide monosolvate.

Project description:The title compound, C22H17NO2·C3H7NO, was synthesized by condensation of an aromatic aldehyde with a secondary amine and subsequent reduction. It was crystallized from a di-methyl-formamide solution as a monosolvate, C22H17NO2·C3H7NO. The aromatic mol-ecule is non-planar with a dihedral angle between the mean planes of the aniline moiety and the methyl anthracene moiety of 81.36?(8)°. The torsion angle of the Car-yl-CH2-NH-Car-yl backbone is 175.9?(2)°. The crystal structure exhibits a three-dimensional supra-molecular network, resulting from hydrogen-bonding inter-actions between the carb-oxy-lic OH group and the solvent O atom as well as between the amine functionality and the O atom of the carb-oxy-lic group and additional C-H?? inter-actions. Hirshfeld surface analysis was performed to qu-antify the inter-molecular inter-actions.

Di-?-chlorido-bis-[chlorido(N,N-di-methyl-ethylenediamine-?N,N')zinc(II)].

Project description:The centrosymmetric dinuclear title compound, [Zn(2)Cl(4)(C(4)H(12)N(2))(2)], is isostructural with its previously reported Cu(II) analogue [Phelps, Goodman & Hodgson (1976 ?). Inorg. Chem.15, 2266-2270]. In the title compound, each of the Zn(II) ions is coordinated by two N atoms from a chelating N,N-dimethyl-ethylenediamine ligand, two bridging Cl atoms and one terminal Cl atom. The coordination environment is distorted square-pyramidal. The Zn-Cl bond distances of the two bridging Cl atoms are distinctly different: the equatorial Cl atom exbibits a Zn-Cl distance of 2.318?(1)?Å and the axial Cl atom exbibits a Zn-Cl distance of 2.747?(2)?Å, which is significantly longer. The mol-ecule can thus be seen as a dimer of two nearly square-planar monomeric units which are related to each other by an inversion center located in the middle of the dimer. Within one monomeric unit, the Zn atom, the two N atoms and the two Cl atoms are almost coplanar, with a mean deviation of only 0.05?(1)?Å from the associated least-squares plane. The Zn?Zn distance within the dimer is 3.472?(3)?Å. N-H?Cl and C-H?Cl hydrogen-bond inter-actions connect neighboring mol-ecules with each other.

Crystal structure of [N,N'-bis-(4-methyl-phen-yl)-1,2-di-phenyl-ethane-1,2-di-imine-κ(2) N,N']di-chlorido-palladium(II) methanol monosolvate.

Project description:The title compound, [PdCl2(C28H24N2)]·CH3OH, was pre-pared from the reaction of PdCl2(DMSO)2 (DMSO is di-methyl sulfoxide) and N,N'-bis-(4-methyl-phen-yl)-1,2-di-phenyl-ethane-1,2-di-imine in methanol. The chelating di-imine core of the title compound deviates slightly from planarity, with an N-C-C-N torsion angle of 5.3 (3)°. Delocalization in the di-imine core is indicated by N-C and C-C bonds that are, respectively, longer and shorter than those found in related nonchelating di-imines. The distorted square-planar coordination environment around the Pd(II) atom is manifested as bond angles that are smaller and larger than 90°, and palladacycle torsion angles of -173.22 (16) and 167.06 (16)°. These deviations are attributed to the small bite angle of 79.13 (8)° of the di-imine chelate. The crystal packing exhibits weak inter-molecular hydrogen-bonding inter-actions involving aromatic H atoms, Cl atoms and inter-calated methanol solvent mol-ecules, defining layers parallel to (010).
