Abstract
The molecular and crystal structure of the [La(NO3)3(H2O)2(2.2′-BiPy)]·1.5(2.2′-BiPy) compound is determined. The metal coordination polyhedron in the La(III) complex is formed from 10 donor atoms of O8N2: 6 oxygen atoms belong to three chelate-coordinated NO −3 anions, 2 oxygen atoms belong to two water molecules, and 2 nitrogen atoms belong to a bidentate bipyridine molecule coordinated in the neutral form. The structure is based on the metal complexes linked together in chains through the O(W)-H...O hydrogen bonds, in which oxygen atoms of the coordinated NO −3 anions act as acceptors. It is a framework structure, further stabilized by a system of O(W)-H...N and C-H...N hydrogen bonds, in which nitrogen atoms of the uncoordinated bipyridine molecules act as proton acceptors.
