  Abstract:   New 1,9-diacyl-5-(phenothiazinyl)dipyrromethane (aphdpm) obtained by diacylation of 5-phenothiazinyl-dipyrromethane were subjected to complexation reactions with dimethyl- and di-n-butyltin(IV) dichloride which afforded complexes of the type [Me2Sn(aphdpm)] and [(n-Bu)2Sn(aphdpm)] respectively [where aphdpm: 1,9-diformyl-5-(phenothiazinyl)dipyrromethane and 1,9-dibenzoyl-5-(phenothiazinyl) dipyrromethane]. Plausible structures of the new tin(IV) complexes were proposed based on spectroscopic FT-IR, 1H-,13C-,119Sn-NMR and mass spectrometry studies.
