Crystal structure and Hirshfeld surface analysis of bis[(ethoxymethanethioyl)sulfanido](N,N,N′,N′-tetramethylethane-1,2-diamine)mercury(II)

ABSTRACT: In the crystal, molecules are linked by weak C—H⋯S hydrogen bonds, forming a two-dimensional supramolecular architecture. The title four-coordinate mononuclear complex, [Hg(C3H5OS2)2(C6H16N2)] or [Hg(C3H5OS2)2(tmeda)] (tmeda: N,N,N′,N′-tetramethylethane-1,2-diamine), has a distorted tetrahedral geometry. The HgII ion is coordinated to two N atoms of the N,N,N′,N′-tetramethylethylenediamine ligand and two S atoms from two ethylxanthate xanthate ligands. In the crystal, molecules are linked by weak C—H⋯S hydrogen bonds, forming a two-dimensional supramolecular architecture in the ab plane. The most important contributions for the crystal packing are from H⋯H (59.3%), S⋯H (27.4%) and O⋯H (7.5%) interactions.

Bis{bis-[1-meth-oxy-2-(2-meth-oxy-eth-oxy)ethane-?(3) O,O',O'']sodium} 1,1,2,2-tetra-phenyl-ethane-1,2-diide.

Project description:Crystals of the title salt, [Na(C6H14O3)2]2(C26H20), were grown from a tetra-hydro-furan/diglyme/Et2O solvent mixture [diglyme is 1-meth-oxy-2-(2-meth-oxy-eth-oxy)ethane]. The cations and dianion are separated in the crystal structure, unlike in the other three structurally characterized dialkali metal tetra-phenyl-ethyl-ene salts. The asymmetric unit contains one [Na(diglyme)2](+) cation and one half of the [Ph2CCPh2](2-) dianion. The latter lies on a twofold rotation axis. C-C bond-length redistribution displays that excessive electron density of the dianion is predominantly located at the C atoms of a former double bond and at all eight ortho positions. The studied crystal was a twin, with the ratio of two major components being 0.2143?(9):0.7857?(9). The twin operation is a twofold rotation around the a axis.

trans-Chloridobis-(ethane-1,2-di-amine-κ(2) N,N')(thio-cyanato-κN)cobalt(III) diammine-tetra-kis-(thio-cyanato-κN)cromate(III).

Project description:The title ionic complex [CoCl(NCS)(C2H8N2)2][Cr(NCS)4(NH3)2], which crystallizes as a non-merohedral twin, is build up of a complex cation [CoCl(NCS)(en)2](+) (en is ethane-1,2-di-amine) and the Reinecke's salt anion [Cr(NCS)4(NH3)2](-) as complex counter-ion. A network of N-H⋯S and N-H⋯Cl hydrogen bonds, as well as short S⋯S contacts [3.538 (2) and 3.489 (3) Å], between the NCS groups of the complex anions link the mol-ecules into a three-dimentional supra-molecular network. Intensity statistic indicated twinning by non-mero-hedry with refined weighs of twin components are 0.5662:0.4338.

1,2-Bis[2-(2-nitro-1H-imidazol-1-yl)eth-oxy]ethane.

Project description:In the crystal structure, the title compound, C(12)H(16)N(6)O(6), lies on an inversion centre. The mol-ecule has an anti-periplanar conformation with respect to the C-C bond of the central ethane unit and the two imidazole rings are parallel to each other. The dihedral angle between the imidazole ring and the mean plane of the C and O atoms of the bis-(eth-oxy)ethane group is 76.04?(6)°. The mol-ecules are stacked along the c axis through a weak C-H?O inter-action and a ??? inter-action between the imidazole rings with a centroid-centroid distance of 3.5162?(6)?Å. An intramolecular C-H?O hydrogen bond is also present.

(E)-{[(Butyl-sulfan-yl)methane-thio-yl]amino}(4-meth-oxy-benzyl-idene)amine: crystal structure and Hirshfeld surface analysis.

Project description:The title hydrazine carbodi-thio-ate, C13H18N2OS2, is constructed about a central and almost planar C2N2S2 chromophore (r.m.s. deviation = 0.0263 Å); the terminal meth-oxy-benzene group is close to coplanar with this plane [dihedral angle = 3.92 (11)°]. The n-butyl group has an extended all-trans conformation [torsion angles S-Cm-Cm-Cm = -173.2 (3)° and Cm-Cm-Cm-Cme = 180.0 (4)°; m = methyl-ene and me = meth-yl]. The most prominent feature of the mol-ecular packing is the formation of centrosymmetric eight-membered {⋯HNCS}2 synthons, as a result of thio-amide-N-H⋯S(thio-amide) hydrogen bonds; these are linked via meth-oxy-C-H⋯π(meth-oxy-benzene) inter-actions to form a linear supra-molecular chain propagating along the a-axis direction. An analysis of the calculated Hirshfeld surfaces and two-dimensional fingerprint plots point to the significance of H⋯H (58.4%), S⋯H/H⋯S (17.1%), C⋯H/H⋯C (8.2%) and O⋯H/H⋯O (4.9%) contacts in the packing. The energies of the most significant inter-actions, i.e. the N-H⋯S and C-H⋯π inter-actions have their most significant contributions from electrostatic and dispersive components, respectively. The energies of two other identified close contacts at close to van der Waals distances, i.e. a thione-sulfur and meth-oxy-benzene-hydrogen contact (occurring within the chains along the a axis) and between methyl-ene-H atoms (occurring between chains to consolidate the three-dimensional architecture), are largely dispersive in nature.

12-Eth-oxy-2,3,8,9-tetra-methoxy-benzo[c]phenanthridine dichloro-methane solvate.

Project description:The title compound, C(23)H(23)NO(5)·CH(2)Cl(2), was obtained via the alkyl-ation of the 12-hydr-oxy-2,3,8,9-tetra-methoxy-benzo[c]phenanthridine salt. The benzo[c]phenanthridine ring system is essentially planar, with a mean out-of-plane deviation of 0.026?Å. A dicloromethane mol-ecule of solvation is present and located between the sheets of phenanthridine mol-ecules, preventing any significant inter-molecular hydrogen-bonding or ?-? inter-actions.

[N,N-Bis(2-amino-eth-yl)ethane-1,2-diamine](ethane-1,2-diamine)-nickel(II) thio-sulfate trihydrate.

Project description:The title compound, [Ni(C(2)H(8)N(2))(C(6)H(18)N(4))]S(2)O(3)·3H(2)O, was accidentally synthesized under solvothermal conditions applying [Ni(en)(3)]Cl(2) (en is ethane-1,2-diamine) as the Ni source. The asymmetric unit consists of one discrete [Ni(tren)(en)](2+) complex [tren is N,N-bis-(2-amino-eth-yl)ethane-1,2-diamine] in which the Ni(2+) cation is sixfold coord-inated within a slightly distorted octa-hedron, one thio-sulfate anion and three water mol-ecules. In the crystal, the complex cations, anions and water mol-ecules are linked by an intricate hydrogen-bonding network. One C atom of the tren ligand, as well as one O atom of a water mol-ecule, are disordered over two sites and were refined using a split model (occupancy ratios = 0.85:15 and 0.60:0.40, respectively).

Bis[N-(2-amino-eth-yl)ethane-1,2-diamine-?N,N',N'']copper(II) tris-[diamminetetra-kis-(thio-cyanato-?N)chromate(III)] thio-cyanate dimethyl sulfoxide tetra-deca-solvate monohydrate.

Project description:The ionic title complex, [Cu(C(4)H(13)N(3))(2)](2)[Cr(NCS)(4)(NH(3))(2)](3)(NCS)·14C(2)H(6)OS·H(2)O, consists of complex [Cu(dien)(2)](2+) cations [dien is N-(2-amino-eth-yl)ethane-1,2-diamine], com-plex [Cr(NCS)(4)(NH(3))(2)](-) anions, an NCS(-) counter-anion and uncoordinated dimethyl sulfoxide (DMSO) and water solvent mol-ecules. One of the Cr atoms lies on an inversion center, while the second Cr atom and the Cu atom lie in general positions. The thio-cyanate counter-anion and water mol-ecule are disordered over two positions close to an inversion center. There are several types of hydrogen-bond inter-actions present in the title compound, which connect the complex cations and anions into bulky [Cu(2)Cr(3)] polynuclear species. The four NH(3) groups of the complex anions and six bridging DMSO O atoms link the three complex anions via hydrogen bonding into the anionic polynuclear species [Cr(NCS)(4)(NH(3))(2)](3)·6DMSO. The last one is connected by four bridging DMSO O atoms with the two complex copper cations through N-H? O hydrogen bonds between the terminal NH(3) groups of the anionic polynuclear species and the NH and NH(2) groups of the dien ligand. One additional DMSO mol-ecule is connected via hydrogen bonding to one of the terminal NH(3) groups of the anionic polynuclear species. Another DMSO mol-ecule is connected via hydrogen bonding to each Cu(dien)(2)](2+) cation.

Crystal structure of bis-[trans-(ethane-1,2-di-amine-κ(2) N,N')bis-(thio-cyanato-κN)chromium(III)] tetra-chlorido-zincate from synchrotron data.

Project description:The structure of the title compound, [Cr(NCS)2(C2H8N2)2]2[ZnCl4], has been determined from synchrotron data. In the asymmetric unit, there are four independent halves of the Cr(III) complex cations, each of which lies on an inversion centre, and one tetra-chlorido-zincate anion in a general position. The Cr(III) atoms are coordinated by the four N atoms of two ethane-1,2-di-amine (en) ligands in the equatorial plane and two N-bound NCS(-) anions in a trans arrangement, displaying a slightly distorted octa-hedral geometry with crystallographic inversion symmetry. The Cr-N(en) and Cr-N(NCS) bond lengths range from 2.0653 (10) to 2.0837 (10) Å and from 1.9811 (10) to 1.9890 (10) Å, respectively. The five-membered metalla-rings are in stable gauche conformations. The [ZnCl4](2-) anion has a distorted tetra-hedral geometry. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the en NH2 or CH2 groups as donors and chloride ligands of the anion and S atoms of NCS(-) ligands as acceptors.
