Synthesis, characterization and structure of the dimmer complex [ni（tssb）（phen）h2o]·c2h5oh·0.5h2o

Abstract

The title complex [Ni(TSSB)(phen)H2O]?C2H5OH?0.5H2O (C23H26N3NiO6.5S, TSSB = taurine salicylaldehyde Schiff base, phen = 1,10-phenanthroline) has been synthesized by the reaction of taurine salicylaldehyde Schiff base (TSSB), 1,10-phenanthroline and nickel acetate in water-ethanol. Its single-crystal structure was determined by X-ray diffraction method. The crystal belongs to triclinic, space group P1 with a = 1.0562(2), b = 1.1604(2), c = 2.1170(3) nm, α = 103.257(3), β = 96.958(4), γ = 105.179(3)°, Mr = 539.24, V = 2.3917(6) nm3, Z = 4, Dc = 1.498 g/cm3, μ = 0.945 mm-1 and F(000) = 1124. The compound is a one-dimensional network, infinitely extending with hydrogen bonds. The Ni(Ⅱ) is 6-coordinated by one nitrogen and two oxygen atoms from taurine salicylaldehyde Schiff base, two nitrogen from 1,10-phenanthroline and one oxygen from water to form a distorted octahedronal coordination geometry.
