Reactions of bitter salt with taurine-3,5-dibromo-salicylaldehyde schiff base gave one new Complex [Mg(Br2TSSB)(Phen)(H2O)]·H2O (Br2TSSB=Taurine 3,5-dibromo-Salicylaldehyde Schiff Base, phen=o-phenanthro- line), ...Reactions of bitter salt with taurine-3,5-dibromo-salicylaldehyde schiff base gave one new Complex [Mg(Br2TSSB)(Phen)(H2O)]·H2O (Br2TSSB=Taurine 3,5-dibromo-Salicylaldehyde Schiff Base, phen=o-phenanthro- line), which was characterized by elemental analysis, IR and X-ray diffraction. The chemical formula weight of the complex is 625.58. It′s crystal belongs to monoclinic system with space group P21/c. The cell parameters are: a=1.8142(3) nm, b=0.81475(14) nm, c=1.641 7(3) nm, β=90.571(4)°, and Z=4, V=2.426 4(7) nm3, Dc=1.712 g· cm-3, F(000)=1248, μ=3.496 mm-1. The complexes form a 3D net structure in which they are connected with hy- drogen bonds and #-# stacking. The Mg! formed a distorted coordination tetragonal pyramid. CCDC: 286194.展开更多

It has been characterized by IR, element analysis and X-ray diffraction analysis. The crystal structure of the title complex belongs to monoclinic space group P21 / c with cell parameters: a=0.999 78(6) nm, b=1.951 11(13) nm, c=1.496 02(10) nm, β=97.126 0(10)°, and V=2.895 7(3) nm3, Dc=1.639 g·cm-3, Z=4, F(000)=1 424, μ=3.647 mm-1, the final R=0.061 0 and wR=0.140 2 for 3 528 observed reflections with I>2σ(I). The X-ray crystal structure analysis revealed that the center zinc(Ⅱ) is bonded to two oxygen atoms and one nitrogen atom from a tridentate ligand and three nitrogen atoms from three solvent pyridine molecules to form a six-coordinate octahedron.
