|
Abstract:
摘要 利用2-(2'-羟基苯)噁唑啉作为配体,通过与不同的锌盐进行反应,得到结构新颖的双核及四核配合物.对该系列化合物用元素分析,红外光谱进行表征.X-射线衍射单晶结构分析发现在配合物1中2-(2'-羟基苯)噁唑啉配体的羟基氧作为单原子桥连接2个锌离子,配合物2中除配体的羟基氧桥之外还存在甲氧基的氧原子桥连3个锌离子.配合物1 属于单斜晶系,空间群为P21,晶胞参数:a=9.384 2 ？(19), b=13.584 0 ？(30), c=11.138 0 ？(20), β=96.250°(30).配合物2属于三斜晶系,空间群为P-1,晶胞参数为 a=9.551 7？(19), b=11.123 4 ？(22), c=11.182 6 ？(22), α=102.820°(30), β=114.988°(30), γ=100.806°(30).对配合物1的甲醇溶液中及固相荧光光谱进行研究,结果显示它有较好的荧光性质.
