2-Hy-droxy-4-meth-oxy-benzaldehyde thio-semicarbazone.

ABSTRACT: The title Schiff base compound, C(9)H(11)N(3)O(2)S, was prepared by the reaction of equimolar quanti-ties of 2-hy-droxy-4-meth-oxy-benzaldehyde with thio-semicarbazide in methanol. The mol-ecule adopts a trans configuration with respect to the azo-methine group and an intra-molecular O-H?N hydrogen bond generates an S(6) ring. In the crystal structure, mol-ecules are linked through inter-molecular N-H?O and N-H?S hydrogen bonds, forming a three-dimensional network.

Project description:The title CoIII complex, bis-[bis-(2-hy-droxy-3-meth-oxy-benzaldehyde thio-semi-carbazonato)cobalt(III)] di-thio-nate-dimethylformamide-methanol (1/4/3), [Co(C9H10N3O2S)2]2(S2O6)·4C3H7NO·3CH3OH, with monodeprotonated 2-hy-droxy-3-meth-oxy-benzaldehyde thio-semicarbazone as ligands crystallizes in the space group P .

Each CoIII ion has a moderately distorted octa-hedral S2N2O2 geometry. In the crystal, the components are linked by numerous N-H⋯O and O-H⋯O contacts.

2-Hy-droxy-3-meth-oxy-benzaldehyde (o-vanillin) revisited.

Project description:The structure of ortho-vanillin, C(8)H(8)O(3), has been revisited with modern methods and at low temperature (100?K). The previous structure [Iwasaki et al. (1976 ?). Acta Cryst. B32, 1264-1266] is confirmed, but geometric precision is improved by an order of magnitude. The C atom of the meth-oxy group lies close to the benzene ring plane, which is the most common geometry for -OMe groups lying ortho to -OH groups on an aromatic ring. The crystal structure displays one intra-molecular O-H?O and three weak inter-molecular C-H?O hydrogen bonds.
