Abstract: The aminocarboxylic acid, phenyliminodiacetic acid [C6H5N(CH2COOH)2, H2L] , was synthesized by the reaction between phenylid and chloroacetic acid. The copper complex with the acid [CuL(H2O)] was obtained in aquo solution and its crystal structure was determined by X-ray diffraction with a final R1 value of 0.0244 and a wR2 value of 0.0660. The crystal is of monoclinic system with a space group P21/C . The unit cell parameters are as follows: a =1.2183(2) nm, b =0.86831(10) nm, c= 0.97940 nm , β =96.100(10)°, V =1.0322(2) nm3, Z =4, Dc=1.862 g/cm3, F (000)=588, μ =2.129 mm-1 . In crystal, each copper ion is coordinated with three oxygen atoms and one nitrogen atom from H2L and an oxygen atom from water; the coordination polyhedron around Cu 2+ is a distorted tetragonal pyramid. Cu 2+ are linked by anti anti carboxyl bridges to form endless zigzag chain, a two dimensional network is obtained through the hydrogen bonds between the adjacent chains.
