L-aspartic acid,1,10-phenanthroline,nickel(H) complex,crystal structure
A new ternary complex of nickel(Ⅱ) with L-aspartate (L-Asp) and 1, 10-phenanthroline(Phen), [Ni3(L-Asp)(Phen)5(H2O)3](ClO4)4.4.75H2O, has been synthesized in a mixed solvent of H2OC2H5OH at the pH value of 3. It crystallizes in triclinic, space group P-1 with a =11.861(2), b = 18.384(4), c = 19.746(3)(°A), α = 107.68(1), β = 105.94(1), γ= 103.41(2)°, V =3703.6(11) (°A)3, Mr = 1745.66, Z = 2, Dc =1.565 g/cm3, u = 0.989 mm-1, F(000) = 1791, R = 0.0643and wR = 0.1611. The complex contains two cations, binuclear [Ni2(L-Asp)(Phen)3(H2O)]2+ and mononu- clear [Ni(Phen)2(H2O)2]2+. All the nickel ions in the complex are six-coordinated with a distorted octahedral geometry, but the coordination environments for them are different. There exist hydrogen bonds and π-π stacking interactions in the complex.
