A novel series of <i>cis</i>-dioxomolybdenum(VI) carbodithioate complexes

810-812Complexes of cis-dioxomolybdenum(VI) having the empirical formulae (MoO2L). 3H2O (where L= piperazinyl- N,N'-bis-carbodithioate, PpzDtc) and MoO2L2 (where L= N'-methylpiperazinyl-N-.carbodithioate, Nmethyl PpzDtc, piperidinyl-N-carbodithioate, PpdDtc, morpholinyl- N-carbodithioate, MorphDtc, 1,2,3 ,4-tetrahydroisoquinolinyl- N-carbodithioate, ThiqDtc and 1,2,3,4-tetrahydroquinolinyl-N-carbodithioate, ThqDtc) have been synthesised and characterized. The physicochemical studies indicate that the ligand in the (MoO2L)' 3H2O complex is bivalent tetradentate and the ligands in the MoO2L2 complexes are univalent bidentate. The oxo groups are cis to each other. The metal is hexacoordinated and the complexes have approximately octahedral geometries
