The complex of the formula [Zn(4, 4'-bpy) (2)(H2O) (2)] (pic) (2) . (H2O) (2) was obtained from the reaction of the zinc picrate and 4, 4'-bipyridine, and characterized by elemental analysis, IR spectrum and X-ray diffraction. It crystallizes in the monoclinic space group Cc with cell parameters a = 1. 4390(2), b = 1. 1418(1), c = 2. 2908(3)nm, beta = 95. 08(1)degrees, V= 3. 749(1)nm(3), Z = 4. It has infinite 2-D network structures, and the 2-D networks are extended into 3-D network structures by packing along the a-axis through hydrogen bonding, exhibiting a certain inclusion phenomenon.
