摘要
The crystal structure, of [Pt(NH_3)_2CPrDCA]. H_2O (Ⅰ), [Pt(CH_3NH_2)_2CPrDCA] (Ⅱ), and [Pt(dmbn) CPrDCA]·2.5H_2O(Ⅲ) (where CPrDCA is 1, 1-cyclopropanedicarboxylate; dmbn is 2, 3-dimethyl-2, 3-butyldiamine) are determined. Compound Ⅰ crystallizes in the orthorhombic space group P_(nma) with the cell dimensions: a=6.517(2), b=9.709(3), c=14.205(5), Z=4, R=0.058. Compound Ⅱ is monoclinic with space group P2_1/n, a=9.648(3), b=8.720(2), c=12.770(4), β=107.12(2), Z=4, R=0.059. Compound Ⅲ belongs to the monoclinic system space group P2_1/m with the cell dimensions: a=6.494(1), b=19.638(3), c=6.606(1), β=94.44(1), Z=2, R=0.038.Electronic structures of the complexes are studied and the correlstion between structure of the amine ligands and biological activity of the complexes is explored.
