Synthesis and structure of fused ring containing phosphorus compound-pyridinium 8, 9, 16,-17-tetradehydro-6,14-dithiono-7,8,15,16-tetraza-5,13-dioxa-6,14-diphospha-dibenzo [a,h] tetradecahydroanthracene-6,14-dithiolate and its derivatives

Abstract

The syntheses of pyridinium of 8,9,16,‐17‐tetradehydro‐6,14‐dithiono‐7,8,15,16‐tetraza‐5,13‐dioxa‐6,14‐diphospha‐dibenzo [a,h] tetradecahydroanthracene‐6,14‐dithiolate and its eleven derivatives were described. The crystal and molecular structures of the pyridinium compound and its several derivatives were also determined.
