NEW STAGE IN DEVELOPMENT OF COORDINATION CHEMISTRY OF AROYL- (PYRYDINOYL)HYDRAZONES OF SUBSTITUTED BENZ-(-1-NAPHTH)ALDEHYDES

Abstract

The information on types of coordination of benzoyl-(2-hydroxybenzoyl-, pyridinoyl-)hy- drazones of benz-(2-hydroxybenz)aldehydes in d-metal complexes is given in the review. The results of systematic investigations of interaction between hydrazones of substituted benz-(-1- naphth)aldehydes and Lewis acids (GeCl4, SnCl4) in methanol (acetonitrile)carried by authors, are generalized. About 45 germanium and tin compounds have been synthesized for the first time (15 of them - X-ray analysis). The influence of structure of hydrazide (R-benzoyl-(R = H, OH, NO2, Cl, NH2), alpha-, beta-, gamma-pyridinoyl-) and aldehyde (benz-, 4-dimethylaminobenz-, 2-hydroxybenz-, 2-hydroxy-1-naphth-) trayments of hydrazone molecule, central ion(Ge(IV), Sn(IV)), solvent nature (CH3OH, CH3CN) on composition, structure of complexes and ligands coordination form have been proved. The prospect of complexes use as anti-inflammatory and antimicrobial drugs have been shown.
