analyzed in terms of salt/cocrystal, deprotonation, synthons, and network geometries. The tetra carboxylic acid, H41, was found to act as a host for the inclusion of acetic acid dimers. For complexation reactions with bases, the mono basic compounds such as pyridine, quinoline, and acridine; the dibasic compounds such as 9,10-phenanthrolene, 4,4′-bipyridylethane, 4,4′-bipyridyldisulfide, phenazine, and 1
合成了2,2',6,6'-四羧基联苯(H 4 1)与各种含氮杂环和N-氧化物的几种配合物,并根据盐/共晶体,去质子,合成子和网络分析了它们的晶体结构几何形状。发现四羧酸H 4 1充当包含乙酸二聚体的主体。对于与碱的络合反应,单碱性化合物如吡啶,喹啉和a啶;二元化合物,例如9,10-菲咯啉,4,4'-联吡啶二乙烷,4,4'-联吡啶二硫化物,吩嗪和1,4-二氮杂双环辛烷(达博科);考虑了4,4'-联吡啶和dabco的N-氧化物。在这些配合物的晶体结构中,H 4 1根据络合剂的碱性和其他因素,发现H 2以H 2 1(H 4 1的双去质子化),H 3 1(H 4 1的单去质子化)或H 4 1(共晶体)形式存在。在这里研究的13种配合物中,在一种配合物中,COO –····································································
