Abstract: Two novel coordination polymers [Cd(NiL)(aipt)](1) and [Mn(nipt)(NiL)2]稨2O(2)(NiL, H2L=2,3-dioxo- 5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien, H2aipt=5-aminoisophthalic acid, H2nipt=5-nitroisoph- thalic acid) were hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Compounds 1 and 2 consist of different 1D chains including both oxamide and 5-aminoisophthalate or 5-nitroisophthalic bridge. And all these chains were further interlinked via hydrogen bonds, resulting in a 2D architecture in compounds 1 and 2.

Key words: Macrocyclic oxamide complex, 5-Aminoisophthalic acid, 5-Nitroisophthalic acid, Heterometallic complex, Polynuclear complex
