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

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

μ-2-Amino­terephthalato-κ2 O 1:O 4-bis­[triphenyl­tin(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

(E)-2-Meth­oxy-6-(thia­zol-2-ylimino­meth­yl)phenol

The title compound, C11H10N2O2S, displays an E configuration about the C=N bond. The mean planes of the thia­zole and benzene rings make a dihedral angle of 9.32 (18)°. Intra­molecular O—H⋯N hydrogen bonds are found in the crystal structure

3-[(3-Oxo-1,3-dihydro­isobenzofuran-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

3,3′-Oxybi[isobenzofuran-1(3H)-one]

The title compound, C16H10O5, consists of two isobenzofuran-1(3H)-one moieties which are linked by a bridging O atom. The two halves of the mol­ecule display approximate non-crystallographic mirror symmetry. The dihedral angle between the two isobenzofuran-1(3H)-one ring systems is 53.18 (6) Å. Two chiral carbon centres are observed in the compound, but their absolute configurations could not be determined. In the crystal structure, inter­molecular C—H⋯O hydrogen bonds link mol­ecules into zigzag chains along c. Additional C—H⋯O inter­actions connect adjacent chains

catena-Poly[[trimethyl­tin(IV)]-μ-2,5-difluoro­benzoato-κ2 O:O′]

In the title polymeric coordination compound, [Sn(CH3)3(C7H3F2O2)]n, the Sn atom exhibits a distorted trigonal-bipyramidal coordination geometry with the carboxyl­ate O atoms in the axial positions and the equatorial positions occupied by the methyl groups. The two Sn—O bond lengths are 2.225 (5) and 2.410 (6) Å

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
