摘要：
Crystal structure of a double Np(V) and Co(NH3)6 3+ maleate Co(NH3)6[NpO2(HL) 2(H2O)3](HL)2·H2O [L = OOC(HC)2COO] was studied. The crystal structure consists of complex anions [NpO2(HL)2(H2O) 3]-, HL- anions, [Co(NH3) 6]3+ cations, and water molecules of crystallization. Hydrogen bonds in which proton donors are water molecules and hexaamminecobalt cations link structural fragments to form a 3D network. The coordination polyhedra of the Np(V) atoms are pentagonal bipyramids whose equatorial planes are formed by oxygen atoms of two HL- anions and three water molecules. Four crystallographically independent maleate anions were identified in the structure. Two of these anions enter into the Np(V) surrounding, and their coordination capacity is 1. © 2004 MAIK "Nauka/ Interperiodica".
