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 was characterized by ele- mental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the title complex [Cu(C9H9BrNO2)2] belongs tomonoclinic, space group P21/ n with a=1.319 1(5)nm, b=0.444 58(16)nm, c=1.656 7(6)nm, β=91.226(5)°, V=0.97146(6) nm3, Z=2, Dc=1.879 Mg·m-3, μ=5.264 mm-1, F(000)=542, and final R1=0.0456, wR2=0.0970. The complex comprises a four-coordinated copper! center, with an N2O2 planar coordination environment. The molecules are connected by hydrogen bonds to form two-dimensional layered structure.
