Abstract: The mixed complex Cu (bipy) [BMA]·3H2O (where BMAH2, stands for benzylmalonic acid) was synthesized and its crystal structure was determined. The crystal belongs to orthorhombic system and space group Pbca with parameters: α=1.6593 (3) nm, b= 1. 4673(3) nm, c=1.6747(3) nm, V=4. 077(2) nm3, Z=8, Dc=1. 52 g/cm3. Final R and Rw are 0. 037 and 0. 038 respectively. The crystal structure shows that the major forces of crystal formation come from the intermolecular aromatic stacking and hydrogen bonding.This intermolecular stacking interaction in the crystal differs from that in other reports.Molecule recognition interaction is found in the crystals.

Key words: Crystal structure, Mixed complex, Aromatic ring stacking, Molecule recognition, Copper complex
