Synthesis and structure of 2D nickel(II) coordination compound with phenyl-iminodiacetic acid

A new nickel(II) coordination compound [Ni(L2-)(2,2'-bipy)(H2O)]-2H(2)O (H2L = phenyliminodiacetic acid) was obtained by self-assembly of phenyliminodiacetic acid, 2,2'-bipy, and NiCl2-6H(2)O in the mixed solvent of water and ethanol (V:V = 1:1). The complex was characterized by elemental analysis, IR spectra, and X-ray crystallography analysis. The crystal is monoclinic, space group P2(1)/c with a = 0.867 4(2) nm, b = 0.907 3 (1) nm, c = 2.643 5(5) nm, beta = 91.01 (1)degrees, V = 2.080 2(4) nm(3), Z = 4, F(000) = 992, D-c = 1.520 Mg-m(-3), R-1 = 0.027 0 and wR(2) = 0.067 5. In the complex, nickel (11) atom is coordinated with a distorted octahedral geometry and extensive hydrogen bonds link the complexes into a 2D network structure.
