Abstract: The reaction of PdCl2in water with 2-hydroxypropane-1, 3-diaminetetraacetic acid (HPDTA) gave the complex Pd (C11H16N2O9)·1. 5H2O, which was characterized by elemental analysis, IR, NMR and single-crystal X-ray diffraction. The spectroscopic and X-ray diffraction data show that Pd (Ⅱ) is coordinated by two nitrogen atoms and two car-boxylic oxygen atoms. The complex crystallizes in monoclinic space group Pcwith a=1. 1240(2), b=1. 1183(2), c=1. 2597(3) nm, β=96. 33(2)°V=1. 5737(6) nm3, Z=4, R=0.038. The structure contains two crystallographically independent molecules which have slightly different orientations and are connected by hydrogen bonds.
