| Abstract: | Thiophosphinate Complexes of Lanthanides. I. Dimeric Dimethylthiophosphinate Compounds of LaIII, PrIII, NdIII, and ErIII By reaction of Na(CH3)2POS] · 1,5 H2O with Ln(ClO4)3 (Ln ? La, Pr, Nd, Er) neutral dimeric complexes are formed. The crystal and molecular structures of Pr((CH3)2POS)3(C2H5OH)(C3H7OH)]2, Pr((CH3)2POS)3 · 3 H2O]2 · 4 H2O and Er((CH3)2POS)3(H2O)2]2 have been determined by single crystal X-ray crystallography. The (CH3)2POS? ions are acting partly as bidentate chelates and partly as monodentate O-donors. The dimers are formed by doubly coordinating oxygen atoms of two ligands. Very strong intramolecular O? H…?S hydrogen bonds exist between noncoordinated S atoms and coordinated water molecules. |
