Dichlorido{4-cyclo-hexyl-1-[1-(2-pyridyl-?N)ethyl-idene]thio-semicarbazidato-?N,S}methyl-tin(IV).

ABSTRACT: The monodeprotonated Schiff base ligand in the title compound, [Sn(CH(3))(C(14)H(19)N(4)S)Cl(2)], N,N',S-chelates to the Sn atom, which is six-coordinated in an octa-hedral environment. The three coordinating atoms along with the methyl C atom comprise a square plane, above and below which are positioned the Cl atoms. The amino group is a hydrogen-bond donor to a Cl atom of an adjacent mol-ecule, the hydrogen bond giving rise to a helical chain extending parallel to [100].

Dichlorido{4-cyclo-hexyl-1-[1-(2-pyridyl-?N)ethyl-idene]thio-semicarbazidato-?N,S}phenyl-tin(IV).

Project description:The Sn(IV) atom in the title compound, [Sn(C(6)H(5))(C(14)H(19)N(4)S)Cl(2)], exists within a distorted octa-hedral geometry defined by the N,N',S-tridentate monodeprotonated Schiff base ligand, two mutually trans Cl atoms, and the ipso-C atom of the Sn-bound phenyl group; the latter is trans to the azo-N atom. The greatest distortion from the ideal geometry is found in the nominally trans angle formed by the S and pyridyl-N atoms at Sn [151.03?(4)°]. With the exception of the cyclo-hexyl group (chair form), the Schiff base ligand is almost planar (r.m.s. deviation of non-H and Sn atoms = 0.053?Å). The nearly orthogonal orientation of the Sn-bound phenyl group [N-Sn-C-C torsion angle = 70.8?(5)°] to the planar portion of the Schiff base allows for the formation of significant intra-molecular C-H?Cl inter-actions which preclude the Cl atoms from participating in N-H?Cl hydrogen bonds. Instead, C-H?? contacts, involving methyl-ene H and the Sn-bound phenyl group, lead to the formation of supra-molecular chains that pack in the bc plane. Connections between these layers are of the type C-H?Cl.

Chlorido(1-cyclo-pentyl-idene-4-ethyl-thio-semicarbazidato-?N,S)diphenyl-tin(IV).

Project description:The Sn atom in the title compound, [Sn(C(6)H(5))(2)(C(8)H(14)N(3)S)Cl], is penta-coordinated with a trigonal-bipyramidal coordination geometry. The 1-cyclo-pentyl-idene-4-ethyl-thio-semicarbazidate (cpetsc) ligand coordinates through the S atom and the N atom bonds to the cyclo-pentyl group, forming a five-membered ring with the Sn center. The chloride ligand and the coordinated N atom are in axial positions. In the crystal structure, inter-molecular N-H?Cl hydrogen bonds form chains along [101].

Chlorido{4-cyclo-hexyl-1-[1-(pyridin-2-yl-?N)ethyl-idene]thio-semicarbazidato-?(2)N(1),S}diphenyl-tin(IV).

Project description:The distorted octa-hedral geometry about the Sn(IV) atom in the title compound, [Sn(C(6)H(5))(2)(C(14)H(19)N(4)S)Cl], is defined by the N,N,S-tridentate Schiff base ligand, two mutually trans ipso-C atoms of the Sn-bound phenyl groups, and the Cl atom which is trans to the azo N atom. The two five-membered chelate rings and pyridyl ring are almost coplanar with the dihedral angle between the outer five-membered chelate and pyridine rings being 5.39?(8)°. Centrosymmetric dimers feature in the crystal packing mediated by N-H?S hydrogen bonds, leading to eight-membered {?HNCS}(2) synthons. The dimeric aggregates are connected into a three-dimensional architecture by C-H?Cl and C-H?? inter-actions, as well as ?-? inter-actions occurring between centrosymmetrically related pyridine rings [centroid-centroid distance = 3.6322?(13)?Å].

n-Butyldichlorido{4-cyclo-hexyl-1-[1-(pyridin-2-yl-?N)ethyl-idene]thio-semi-carb-azi-dato-?²N¹,S}tin(IV).

Project description:Two independent mol-ecules comprise the asymmetric unit in the title compound, [Sn(C?H?)(C??H??N?S)Cl?]. In each mol-ecule, the Sn(IV) atom exists within a distorted octa-hedral geometry defined by the N,N',S-tridentate mono-deprotonated Schiff base ligand, two mutually trans Cl atoms, and the ?-C atom of the n-butyl group; the latter is trans to the azo-N atom. The greatest distortion from the ideal geometry is found in the nominally trans angle formed by the S and pyridyl-N atoms at Sn [151.72?(7) and 152.04?(7)°, respectively]. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by a combination of N-H?Cl, C-H?? and ?-? inter-actions [inter-centroid distances = 3.6718?(19) and 3.675?(2)?Å].

n-Butyl-dichlorido{4-cyclo-hexyl-1-[phenyl(2-pyridyl-?N)methyl-ene]-thiosemicarbazidato-?N,S}tin(IV) chloro-form monosolvate.

Project description:The monodeprotonated Schiff base ligand in the title com-pound, [Sn(C(4)H(9))(C(19)H(21)N(4)S)Cl(2)]·CHCl(3), N,N',S-chelates to the Sn atom, which is six-coordinated in an octa-hedral environment. The three coordinating atoms along with the butyl C atom comprise a square plane, above and below which are positioned the Cl atoms. The amino group is a hydrogen-bond donor to a Cl atom of an adjacent mol-ecule, the hydrogen bond giving rise to a helical chain propagating in [010]. The Cl and H atoms of the chloro-form mol-ecule are disordered over two positions in an 0.67:0.33 ratio.

Chloridodiphen-yl{[1-(1,3-thia-zol-2-yl-?N)ethyl-idene]-4-phenyl-thio-semicarbazidato-?N,S}tin(IV) methanol monosolvate.

Project description:The title compound, [Sn(C(6)H(5))(2)(C(12)H(11)N(4)S(2))Cl]·CH(4)O, is formed during the reaction between 2-acetyl-thia-zole 4-phenyl-thio-semicarbazone (Hacthptsc) and diphenyl-tin(IV) dichloride in methanol. In the crystal structure, the Sn atom exhibits an octa-hedral geometry with the [N(2)S] anionic tridentate thio-semicarbazone ligand having chloride trans to the central N and the two phenyl groups trans to each other. The Sn-Cl distance is 2.5929?(6), Sn-S is 2.4896?(6) and Sn-N to the central N is 2.3220?(16)?Å. The MeOH mol-ecules link the Sn complexes into one-dimensional chains via N-H?O and O-H?Cl hydrogen bonds.

3-[(Cyclo-hexyl-idene)amino]-1-(4-methyl-phen-yl)thio-urea.

Project description:In the title compound, C(14)H(19)N(3)S, the cyclo-hexane ring has a chair conformation. The almost planar amino-thio-urea unit (r.m.s. deviation = 0.0062?Å) is aligned at a dihedral angle of 45.23?(8)° with respect to the benzene ring. Inter-molecular N-H?N and N-H?S hydrogen bonding stabilizes the crystal structure.

Crystal structure of 3-benzyl-1-[(cyclo-hexyl-idene)amino]-thio-urea.

Project description:The conformation of the title compound, C14H19N3S, is partially determined by an intra-molecular N-H⋯N hydro-gen-bond inter-action, although the N-H⋯N angle of 108° is quite small. The cyclo-hexyl-idene ring has a chair conformation and its mean plane is inclined to the benzene ring by 46.30 (8)°. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers, with an R 2 (2)(8) ring motif. The dimers are reinforced by pairs of C-H⋯S hydrogen bonds, and are linked by further weak C-H⋯S hydrogen bonds, forming chains propagating along [100].
