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.
The new compound, Ni(TSSB)(Phen)(H2O)·4H2O (TSSB=Taurine Salicylic Schiff Base, phen=O- Phenanthroline) has been synthesized and characterized by IR, elemental analysis and X-ray diffraction. The compound crystal data: triclinic, space group P1, a=1.0497(2), b=1.1225(2), c=2.3843(4) nm, α=87.676(3)°, β= 82.957(3)°, γ=62.924(3)°; V=2.482 3(7) nm3, Z=4; Dc=1.488 g·cm-3, μ=0.920 mm-1, F(000)=1 160, Goof=1.032, (Δρ)max=899 e·nm-3, (Δρ)min=- 624 e·nm-3. The compound is a dimmer. In the complex, two Ni! were coordinated by three oxygen atoms and three nitrogen atoms while the O atoms of Ac- groups did not coordinate. The Ni! formed a distorted octahedron geometry. The compound is an three dimensional net connecting with hydrogen bonding. CCDC: 275474. The TG-IR of the complex was analyzed. The kinetics of the thermal decomposition reaction of the complex was studied under a non isothermal condition by TG-IR. TG and DTG curves indicate that the complex decom- posed in four stages: Ni(TSSB)(phen)H2O·4H2O Ni(TSSB)(phen)H2O Ni(TSSB)(phen) Ni(TSSB)
