In the molecule of 1,the Co（II） cation is coordinated by three O-atoms of two 5-NH2-bdc ligands,one N-atom of another 5-NH2-bdc ligand,one O-atom of 4,4＇-dpdo and one terminal O-atom of water molecule. The molecules construct a 2-D network through bridging 5-NH2-bdc and 4,4＇-dpdo ligands,and further form a 3-D network through N–H and O–H hydrogen bonds. The network topology of 1 can be simplified as a rare 2D （3,6）-connected （426381） net.

Syntheses and Structures of Two Coordination Polymers Containing Macrocyclic Oxamide and Isophthalic Acid Derivatives

Two novel coordination polymers [Cd（NiL）（aipt）]（1） and [Mn（nipt）（NiL）2]？H2O（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.
