七配位K[InⅢ(Hdtpa)]·3.5H2O配合物的合成及结构测定
Synthesis and Structure Determination of Seven-coordinate K[InⅢ (Hdtpa)] · 3.5H2O
摘要
Abstract
In this paper, the title complex K[InⅢ (Hdtpa)] · 3.5H2O(dtpa=diethylenetriaminepentaacetic acid) was synthesized and its crystal structure was determined by single-crystal X-ray structure analysis.The crystal belongs to monoclinic system, P21/c(No. 14) space group with a= 0. 978 1 (2) nm,b=0. 733 8(1) nm, c=2. 962 9(6) nm, β=91.81(3)°, V=0. 212 6(1) nm3, Z=4, M=606.31, Dx=1.895 g · cm-3, μ=1. 382 1 mm-1, F(000)=1 228, R=0. 035 and Rw=0. 041 for 2 802 unique reflections. The complex anion [InⅢ (Hdtpa)]- has a pseudo-monocapped trigonal prismatic sevencoordination structure in which the seven coordinate atoms, three N and four O atoms, are all from a ligand dtpa. In addition, it can be seen that the complex anion [InⅢ (Hdtpa)]- can furnish a free carboxyl group(-CH2COOH) being used for molecular embellishment to form the target diagnosis- and treat-drug of anticancer.关键词
