A novel composite, [C16H36N][Cu(2,2-bipy)3][PW12O40]·CH3CN·H2O based on Keggin-type phosphotungstate, has been synthesized in acetonitrile at moderate
2-Thioxo-1,2-dihydrobenzo[d][1,3]thiazin-4-one(TDBTO),a new thiazin-one derivative,was synthesized and investigated.The crystal structure of TDBTO(C8H5NOS2,Mr =
