Abstract: | Thiophosphinate Complexes of Lanthanides. II. Molecular Structures of [Nd((cyclo-C6H11)2POS)3(H2O)]2 and NH4[Er((cyclo-C6H11)2POS)4(H2O)2] The title compounds are formed by the reaction of NH4((C6H11)2POS) and Ln(ClO4)3 (Ln ? Nd3+, Er3+). Their structures have been determined by single crystal X-ray diffraction. In the dimeric compound, the (C6H11)2POS? ions act partly as bidentate chelates and partly as monodentate O-donors. The dimers are formed by doubly coordinating oxygen atoms of two ligands. In the ionic compound, Er is only sixfold (octahedrally) coordinated by the oxygen atoms of 4 ligands and two water molecules. The structures of so far known thiophosphinate complexes of lanthanides are discussed with respect to stereochemistry and ligand bonding. |
