摘要
The crystal structure of a dioxalate complex Co(NH3) 6NpO2(C2O4)2·1. 5H2O was studied. The structure consists of centrosymmetrical dimeric anions [NpO2(C2O4)2] 26-, [Co(NH3)6]3+ cations, and water molecules of crystallization. The NpO2+ dioxocations have close Np-O bond lengths (average 1.824 Å) and are noticeably bent (ONpO angle 175.6°). Each dioxocation in the [NpO 2(C2O4)2]26- anion is surrounded by five oxygen atoms of three C2O 42- anions; the Np coordination polyhedra are pentagonal bipyramids sharing a common edge. ©2005 Pleiades Publishing, Inc.
