Özet

The Schiff base ligand (1), [C15H17NO] crystallizes in the monoclinic space group P2(1)/c with a = 10.054(3), b = 10.313(3), c = 13.173(4)Angstrom, beta = 107.42(4)degrees, V = 1303.2(7)Angstrom(3), Z = 4, DX = 1.159 g cm(-3), and mu(MoK alpha) = 0.674 cm(-1). The C2-O [1.23(1)Angstrom] and C3-C4 [1.33(2)Angstrom] bond lengths are short, due to its quinoidal structure. In the Schiff base nickel complex (2), [Ni(C16H18NO)(2)] the asymmetric unit is comprised of two half-complexes. It crystallizes in the triclinic space group P1 with a = 5.124(3), b = 16.227(3), c = 16.886(4)Angstrom, alpha = 95.47(8), beta = 96.00(1), gamma = 90.71(4)degrees, V = 1389.6(9)Angstrom(3), Z = 2, DX = 1.289 g cm(-3), and mu(MoK alpha) = 12.1 cm(-1). The coordination of the Ni(II) ions are square planar with bond angles between 87.9(1) and 92.1(1)degrees. The Ni-O and Ni-N distances are 1.819(2), 1.922(2) and 1.823(2), 1.914(3)Angstrom in these two complexes.
