Synthesis, Characterization, and Crystal Structures of Nickel Complexes Derived from N,N′-Bis(3,5-dichlorosalicylidene)-1,3-pentanediamine and N,N′-Bis(3-methylsalicylidene)-1,2-ethanediamine
摘要:
Two new mononuclear Schiff base nickel(II) complexes, [Ni(ClSal)] (1) and [Ni(MeSal)] (2) (H(2)ClSal = N,N '-bis(3,5-dichlorosalicylidene)-1,3-pentanediamine; H(2)MeSal = N,N '-bis(3-methylsalicylidene)-1,2-ethanediamine), have been synthesized and characterized by elemental analyses, infrared spectra, and single-crystal X-ray diffraction. Complex 1 crystallizes in the orthorhombic space group P2(1)2(1)2(1), with unit cell dimensions a = 9.788(1) angstrom, b = 10.206(1) angstrom, c = 20.458(2) angstrom, V = 2043.7(4) angstrom(3), Z = 4, R (1) = 0.0814, and wR (2) = 0.1689. Complex 2 crystallizes in the monoclinic space group P2(1)/n, with unit cell dimensions a = 11.6353(5) angstrom, b = 11.8807(6) angstrom, c = 12.8241(6) angstrom, beta = 115.213(1)degrees, V = 1603.9(1) angstrom(3), Z = 4, R (1) = 0.0243, and wR (2) = 0.0675. The Ni atoms in the complexes are four-coordinated in square planar geometry by the N2O2 donor set of the ligands.
