Hydrothermal synthesis and crystal structure of 3D 2-fold interpenetrating Cu(I) complexes

This paper presents a novel and distinctive metal-organic compound Cu(4,4′-bpy)(H2PO4)·2H2O (4,4′-bpy=4,4′-dipyridyl) 1 with intriguing structure motifs of interpenetrating networks. Furthermore, IR, element analysis, and TGA were employed to characterize it. Compound 1 belongs to monoclinic system, space group P2/n, a=8.4828(15) Å, b=8.8988(16) Å, c=17.862(3) Å, β=102.575(2)°, V=1316.0(4) Å3, Z=4, R1=0.0472.
