摘　　要：The reactions of transition metal salts with taurine 5-chlorosalicylaldelyde Schiff base gave two complexes [Ni(TCSSB)(H2O)3]旽2O (1) and [Cu(TCSSB)(H2O)2]2昜Cu(TCSSB)2]?H2O (2) (TCSSB=taurine-5-chlorosali- cylaldelyde Schiff base), which were characterized by elemental analysis and X-ray diffraction analysis. The com-plex 1 crystallized in monoclinic system with space group P2 1/c, and a=1.4816(2) nm, b=1.3953(2) nm, c=0.7466(1) nm, =100.499(3), V=1.5176(4) nm3, Z=4, and an infinite 3-D network structure was formed by hy-drogen bonds among sulfo group, crystal water and coordinated water. Complex 2 crystallized in triclinic system with space group Pī, with the cell parameters: a=0.6413(2) nm, b=1.4596(3) nm, c=1.6188(4) nm, =102.473(5), 猓?8.979(4), =101.739, V=1.4165(6) nm3, Z=1. The coordination environment between Cu(1) and Cu(2) is different. Cu(1) is slightly distorted square pyramidal while Cu(2) is distorted square-plane. The com-plex 1 is mononuclear while the complex 2 is made up of two coordinated subunits, namely [Cu(TCSSB)2] and [Cu(TCSSB)(H2O)2]2. Besides that the TG-DTG of the complex 1 was analyzed, the thermal decomposition reac-tion of the complex was studied under a non-isothermal condition by TG-DTG. The TG and DTG curves indicate that the complex was decomposed in three stages: [Ni(TCSSB)(H2O)3]旽2Oo260104 CHO--→ Ni(TCSSB)(H2O)3o2110155 C3HO--→ Ni(TCSSB)o425610 CTCSSB--→ NiOThe reactions of transition metal salts with taurine 5-chlorosalicylaldelyde Schiff base gave two complexes [Ni(TCSSB)(H2O)3]旽2O (1) and [Cu(TCSSB)(H2O)2]2昜Cu(TCSSB)2]?H2O (2) (TCSSB=taurine-5-chlorosali- cylaldelyde Schiff base), which were characterized by elemental analysis and X-ray diffraction analysis.
