Abstract
The synthesis and characterization of new complex monoaza and pentaaza angular phenothiazine derivatives is reported. The first derivative, 6,10-Dichloro-17-azadibenzo[a,n]triphenodithiazin-5,11-dione10 was obtained by a base-catalyzed reaction of 2,6-diaminopyridine-3,5-dithiol 5and 2,3-dichloro-1,4-naphthaquinone 9, while that of the second derivative, 7,9,15,17-tetraamino-6,8,16,18,25-pentazadibenzo[a,n]di([1,4]benzothaizino[3,2-c,l])triphenodiathizine (11) was achieved by the reaction of two moles of 2, 4, 6-triaminopyrimidine-3-thiol (8) and one mole compound (10) under the same reaction conditions.. The assigned structures to the above synthesized compounds were done on the basis of spectroscopic analysis.

Keywords
