Komplexe zweifach positiver Übergangsmetallkationen mit Hydrazido-thiophosphorsäure-estern/ Complexes of Divalent Transition Metals with Hydrazido Thiophosphoric Acid Esters

Abstract

<jats:title>Abstract</jats:title><jats:p> Dihydrazido thiophosphoric acid phenyl ester, (NH<jats:sub>2</jats:sub>NH)<jats:sub>2</jats:sub>P(= S)-OC<jats:sub>6</jats:sub>H<jats:sub>5</jats:sub> (DHTPPH), forms a 2:1 complex with manganese(II) chloride: [Mn(II)(DHTPPh)<jats:sub>2</jats:sub>Cl<jats:sub>2</jats:sub>], soluble in methanol. Solvolysis yields the corresponding methyl ester complex. With water in methanol the dihydrazidothiophosphato complex [Mn(II){(NH<jats:sub>2</jats:sub>NH)<jats:sub>2</jats:sub>P(= O)S}<jats:sub>2</jats:sub>] is formed. Monohydrazido thiophosphoric acid diphenyl ester NH2NH-P(= S)(OC<jats:sub>6</jats:sub>H<jats:sub>5</jats:sub>)<jats:sub>2</jats:sub> (MHTPPh) gives various complexes with first row transition metals: [M(II)(MHTPPh)<jats:sub>n</jats:sub>X<jats:sub>2</jats:sub>], n = 2, 4; X = halogen. The nickel complex (n = 4; X = Cl) is characterized by elemental analysis and spectroscopic methods. MHTPPh is monodentate through the terminal N atoms of the hydrazido groups. Iron(II) and cadmium complexes have different compositions (n- 2; X = Cl) and therefore different structures, probably with MHTPPh as a bidentate chelate ligand. </jats:p>
