SYNTHESIS, CHARACTERIZATION AND STRUCTURE DETERMINATION OF YTTRIUM COMPLEX WITH IMINODIACETIC ACID

The title complex was synthesized and its crystal structure Was determ ined by single crystal X-ray diffraction technique with a four circle diffractometer to give final R-1 value 0.050 9 and WR2 value 0.133 7. The crystal is triclinic with space group <P(1)over bar>. The unit cel l parameters are: a = 0.925 4(1) nm, b = 0.992 2(1) nm, c = 1.065 8(2) nm, a = 71.481 (10)degrees, beta = 77.950(10)degrees, gamma = 65.350( 10)degrees, V = 0.840 1(2) nm(3), Z = 2, D-c = 2.034 g/cm(3). The comp lex is a two-dimensional polymeric molecule. In addition, every yttriu m atom is coordinated by four oxygen atoms from four iminodiacetic aci d molecules and four oxygen atoms from water molecules. The coordinati on number of yttrium ion is 8 and the coordination polyhedron is a dis torted trigondodecahedron.
