A zinc complex with ligand N,N''-bis(p-carboxyphenylaminocarbonylmethyl)-N,N',N''-trihy- droxycarbonylmethyl diethylenetriamine, ZnH3L•4H2O (H5L=C28H33N5O12), has been synthesized and characterized by elemental analysis, IR, UV and thermogravimetry. The crystal structure of the complex was determined by X-ray diffraction method. It belongs to triclinic system with P1 space group and a=0.8442(2) nm, b=1.0837(3) nm, c=1.9082(6) nm, α=104.052(5)°, β=94.624(5)°, γ=93.093(5)°, Z=2, R1=0.0547, wR2=0.1306. The structure was solved by direct methods. The Zn(II) cation coordinates to one amide oxygen atom, two amino nitrogen atoms and two carboxy oxygen atoms of the ligand, forming a distorted trigonal bipyramid. The molecules of the complex are linked through hydrogen bonding to form three-dimensional network.
