摘要：
Complexes [Co(tren)(Tsal)]ClO4. H2O 1 and [Ni(pn)(py)(2)(NCS)(2)](2)] (tren = tris(2-aminoethyl)amine, Tsal = thiosalicylate ion, pn = 1, 2-diamino propane and py = pyridine) have been synthesized and structurally characterized. Both complexes crystallize in the monoclinic space group C2/c with a = 21.3340(6), b = 11.7754(2), c = 14.8076(5) Angstrom, beta = 100.3831(10)degrees, Z = 8 (1), and a = 7.2573(8), b = 17.8810(11), c = 15.2681(12) Angstrom, beta = 101.170(2)degrees, Z = 4 (2). The metal atoms in both cases have distorted octahedral geometry. In 1, the tren ligand is quadridentate and Tsal is bidentate chelate. In 2, the pn ligand forms a bidentate chelate with the NCS Ligands in trans positions. Complex 1 is diamagnetic whereas 2 shows paramagnetism with a magnetic moment of 3.10 B. M.
