Di-micro-acetato-O:O'-di-micro-acetato-O,O':O'-bis{[(cyclopentadienyl)tris(dimethylphosphito-P)cobalt-O,O',O"]neodymium(III)}

Abstract

In the title compound, [{eta(5)-CpCo[P(O)(OMe)(2)](3)}Nd(O(2)CCH(3))(2)](2), with a centrosymmetric molecule, each Nd atom has an eight-coordination environment, surrounded by a tripodal {L(OMe) = CpCo[P(O)(OMe)(2)](3)} and four bridging acetato ligands. The coordination geometry around each Nd centre is described as a distorted square-antiprism and the two different types of acetato ligands have micro-O:O'- and micro-O,O':O'-acetato coordination modes. The Nd-O distances are in the range 2.378 (4)-2.594 (5) A and the Nd.Nd distance is 3.9913 (6) A.
