N′-[(E)-3-Pyridylmethyl­idene]benzo­hydrazide

The title compound, C13H11N3O, was prepared by the reaction of benzohydrazide and nicotinaldehyde. The dihedral angle between the planes of the two aromatic rings is 47.78 (9)°. The crystal structure is stabilized by intermolecular N—H⋯N hydrogen-bonding interactions.

Octa­butyl­bis{(E)-2-[4-(2-hydroxy­benzyl­ideneamino)phen­yl]acetato}di-μ2-methoxo-di-μ3-oxido-tetra­tin(IV)

The title compound, [Sn4(C4H9)8(C15H12NO3)2(CH3O)2O2], is a centrosymmetric dimer and displays a ladder type structural motif. There are four SnIV centres which can be divided into two sorts, viz. two endocyclic and two exocyclic. The endo- and exocyclic SnIV centres are linked by bidentate deprotonated methanol and μ3-O atoms. Each exocyclic SnIV centre is also coordinated by a monodentate 2-[4-(2-hydroxybenzylideneamino)phenyl]acetate ligand. Parts of the butyl groups were found to be disordered over two sets of sites.

catena-Poly[[trimethyl­tin(IV)]-μ-2-(3-thien­yl)acetato]

The title compound, [Sn(CH3)3(C6H5O2S)]n, forms an infinite chain structure parallel to [100]. There are two molecules of the complex in the asymmetric unit. The geometry of the Sn atoms in both molecules is distorted trigonal-bipyramidal. The S and C atoms of the thiophene rings in both molecules are disordered over two sites with site-occupancy factors 0.799 (9)/0.201 (9) and 0.618 (7)/0.382 (7), respectively.

catena-Poly[[trimethyl­tin(IV)]-μ-2-(2-chloro­phenyl)­acetato]

In the title polymeric coordination compound, [Sn(CH3)3(C8H6ClO2)]n, the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxylate O atoms of the 2-chlorophenylacetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chlorophenylacetato ligand, forming a chain structure.

3-[(3-Oxo-1,3-dihydro-isobenzofuran-1-yl)amino]benzoic acid.

In the title compound, C15H11NO4, the dihedral angle formed by the benzene ring and isobenzofuran ring system is 67.82 (5) Å. The crystal structure is stabilized by intermolecular O—H⋯O and N—H⋯O hydrogen-bonding interactions.

Tris(O-cyclo-hexyl dithio-carbonato-κS)anti-mony(III).

In the molecule of the title compound, [Sb(C7H11OS2)3], the antimony(III) is coordinated by the S atoms of three O-alkyl xanthate groups acting as monodentate ligands, forming a distorted trigonal-pyramidal coordination.

μ-2-Amino-terephthalato-κO:O-bis-[triphenyl-tin(IV)].

The title compound, [Sn2(C6H5)6(C8H5NO4)], contains two triphenyltin groups bridged by a 2-aminoterephthalate ligand. The two SnIV centers have similar distorted tetrahedral coordination geometries. Each SnIV atom is bonded to three phenyl C atoms and one O atom from a carboxylate group. The other O atom of the carboxylate group has a weak interaction with the Sn atom. The amino group is disordered over two sites, with site-occupancy factors of 0.779 (11) and 0.221 (11). Intramolecular N—H⋯O hydrogen bonds are observed.
