Abstract
In the title compound, {[Zn(C10H8N2)(H2O)4](C4H2O4)·4H2O}n, the ZnII atom is coordinated by two N atoms from two μ-4,4′-bipyridine ligands and four water molecules in a distorted octahedral geometry. The coordination unit is extended through the Zn—N bond, leading to a one-dimensional cationic chain. A twofold rotation axis passes through the Zn atom and along the axis of the 4,4′-bipyridine ligand. Each uncoordinated water molecule acts as both hydrogen-bond donor and acceptor. A three-dimensional network is constructed through hydrogen bonds involving water molecules and fumarate dianions.

Summary
Tmin = 0.626, Tmax = 0.712 catena-Poly[[tetraaqua(l-4,40 -bipyridinej2N:N0 )zinc(II)] fumarate tetrahydrate]. R factor = 0.041; wR factor = 0.113; data-to-parameter ratio = 14.2. In the title compound, {[Zn(C10H8N2)(H2O)4](C4H2O4)4H2O}n, the ZnII atom is coordinated by two N atoms from two -4,40 -bipyridine ligands and four water molecules in a distorted octahedral geometry. The coordination unit is extended through the Zn—N bond, leading to a onedimensional cationic chain. A twofold rotation axis passes through the Zn atom and along the axis of the 4,40 -bipyridine ligand. Each uncoordinated water molecule acts as both hydrogen-bond donor and acceptor. A three-dimensional network is constructed through hydrogen bonds involving water molecules and fumarate dianions
