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

Abstract

Complexes 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 <i>cis </i> to each other. The metal is hexacoordinated and the complexes have approximately octahedral geometries.
