Adducts of mononuclear oxomolybdenum(IV)O,O'-dialkyl(alkylene) dithiophosphate complexes with pyridine, 2,2'-bipyridyl and 1, 10-phenanthroline

Abstract

Equimolar adducts of mononuclear oxomolybdenum(IV)O,O'-dialkyl and alkylene dithiophosphates with heterocyclic amines, MoO[S₂P(OR)₂]₂·L (where when R=Et,i-Bu; L=pyridine and when R=Et,n-Pr,i-Bu; L=2,2'-bipyridyl, 1,10-phenanthroline) and (where G=CH₂CMe₂CH₂, L=2,2'-bipyridyl and when G=CMe₂CMe₂; L=pyridine) have been prepared by reacting the corresponding oxomolybdenum(IV) complexes with an excess of pyridine or with bipyridyl or phenanthroline in a 11 molar ratio. The complexes have been characterized by elemental analyses and molecular weight determinations. Their probable structures are proposed on the basis of i.r. and n.m.r. (¹H,¹³C and ³¹P) spectral data, which are consistent with a 6-coordinated octahedral structure for all the base adduct complexes.
