Poly[[diaquatris(₂-4,4'-bipyridine-²N,N')tetrakis(phenylacetato-O)dinickel(II)] dihydrate]

X.-L. Zhang and S. W. Ng

Abstract: The polymeric title molecule, {[Ni₂(C₈H₇O₂)₄(C₁₀H₈N₂)₃(H₂O)₂]·2H₂O}_n, lies on a center of symmetry at the mid-point of the C_pyridine-C_pyridine bond of one of the two 4,4'-bipyridine molecules that link the adjacent aquanickel(II)-dicarboxylate units into a linear chain. The other 4,4'-bipyridine molecule connects adjacent chains into a square (C₁₀H₈N₂)₃Ni₂ grid. The ladder-like layer structure is disordered in all the organic groups bonded to the metal atom; the uncoordinated water molecules interact within the layers through hydrogen bonds.
