Synthesis and Crystal Structure of Zn(II) Complex with Tridentate Ligand N-(2-Hydroxy-1-naphthylidene)-L-serine

A new Zn(II) complex, [Zn(L)2(H2O)2], where H2L = N-(2-hydroxy-1-naphthyli- dene)-L-serine, has been synthesized and characterized by single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group C2/c with a = 13.669(2), b = 6.4657(9), c = 31.463(5) ?, β = 98.010(2)o, V = 2753.6(7) ?3, Z = 8, Mr = 358.64, Dc = 1.730 g/cm3, F(000) = 1472, μ(MoKα) = 1.814 mm–1, the final R = 0.0355 and wR = 0.0706. The Zn(II) atom adopts a square-pyramidal geometry coordinated by the tridentate ligand and two water molecules. Intermolecular hydrogen bonds link the complex molecules into a two-dimensional layer.
