synthesized and characterized by elemental analysis, IR, TGA, PXRD and single-crystal X-ray crystallography. The structural analysis reveals that complex 1 is a 3D framework built from nanosized acylamide-containing tetracarboxylate ligands (L4−) and dinuclear [Co2(CO2)4] secondary building units (SBUs), exhibiting a uninodal (4,4)-connected crb topology with the Schläfli symbol of (4•65). The desolvated complex
一种新的钴(II)-有机骨架,[Co 2(L)(py)2(DMSO)] n •0.5 n DMF•2 n DMSO(1)[H 4 L = 5,5׳-((萘- 2,6-二羰基)双(氮杂二烷基)二间苯二甲酸,py =吡啶,DMSO =二甲基亚砜,DMF = N,N-二甲基甲酰胺],已通过溶剂热合成并通过元素分析,IR,TGA,PXRD和单-晶体X射线晶体学。结构分析表明,配合物1是一个3D框架,由纳米级的含酰基酰胺的四羧酸盐配体(L 4−)和双核[Co 2(CO 2)4构成]二级建筑单元(SBU),具有单节点(4,4)连接的crb拓扑,其Schläfli符号为(4•6 5)。脱溶剂的配合物(1a)对CO 2的吸附能力比对N 2的吸附能力强,这可能是由于骨架中CO 2分子与酰胺基之间的结合亲和力较强。磁性研究表明,在配合物1中观察到了主要的反铁磁相互作用。
