The combination of both 4,4'-bipyridine(4,4'-bipy) and dihydrogen phosphate anion ligands with copper II results in the formation of a novel layered compound Cu (4, 4'-bipy)(2) (H2PO4)(2) (H2O)(2). The crystal structure comprises discrete. neutral Cu(4,4'-bipy)(2) (H2PO4)(2) (H2O)(2) units. The copper atom, located on the crystallographic twofold axis, is coordinated with two nitrogen atoms of terminal 4,4'-bipy ligands and two water molecules at the equatorial positions, and two dihydrogen phosphate oxygen atoms at the axial positions, forming an elongated octahedron. The complex is a two-dimensional distorted rhomboidal network possessing two kinds of rhomboids with dimensions of ca. 1.6792 nm X 0.3203 nm and 1.2778 nm X 0.3198 nm, respectively. The two-dimensional networks are stacked parallelly on each other. along c-axis to give an extended three-dimensional channel network with an interlayer distance of ca. 0.5030 nm. Crystal data: triclinic, space group P-1(-), a = 1.0253 (2) nm, b = 1.4501 (3) nm, c = 0.79715 (16) nm, a = 97.91 (3)degrees, beta = 90-99(3)degrees, gamma=85.54(3)degrees, V=1.17030(4) nm(3), Z=2, R=0.0892. wR=0.2451.
