摘要：The complexes of alpha-alanine-salicylal Schiff base of magnesium (alpha-ASSM), beta-alanine-salicylal Schiff base of magnesium (beta-ASSM) and taurine-salicylal Schiff base of magnesium (TSSM) were synthesized. The formulae of the complexes are Mg[OC(6)H(4)CHNCH (CH(3))COO]center dot 2H(2)O, Mg[OC(6)H(4)CHNCH(2)CH(2)COO]center dot 2H(2)O and Mg[OC(6)H(4)CHNCH(2)CH(2)SO(3)]center dot 2H(2)O. The crystal structure belongs to orthorhombic system with the lattice parameters: a=1.6954 nm, b=2.0873 nm and c=2.3037 nm for the alpha-ASSM, to orthorhombic system with the lattice parameters: a=1.5586 nm, b=1.8510 nm and c=2.6240 nm for the beta-ASSM, to monoclinic system with the lattice parameters: a=1.3232 nm, b=1.4960 nm, c=2.1543 nm and beta=98.04 degrees for the TSSM, respectively. The results of the thermal decomposition processes and infrared spectra of the complexes show that the complexes may possess different coordination structures.
