Two new Cu compounds, [Cu(3,5,6-tcpa)2(H2O)4]·[Cu(3,5,6-tcpa)2(H2O)2] (1) and [Cu2(3,5,6-tcpa)2(2,2′-bipy)2(oxa)]·2EtOH (2) (3,5,6-Htcpa = 2-((3,5,6-trichloro pyridin-2-yl)oxy)acetic acid, 2,2′-bipy = 2,2′-bipyridine, oxa = oxalate dianion), were synthesized by solvothermal method and systematically characterized. Single-crystal x-ray diffraction anal. show that 1 is an interesting double mononuclear co-crystal and consists of two discrete and stereochem. different complexes: one octahedral, the other tetrahedral about the Cu centers. While for 2, two equivalent Cu ions are in square pyramidal geometry and linked by oxalate anion forming a novel binuclear cluster. The O-H···O H bonds, Cl···Cl halogen bonds and/or π···π stacking interactions play an important part in construction of the 3-dimensional networks for 1 and 2. The magnetic measurements indicate that there is weak antiferromagnetic coupling between two Cu ions in 1 and 2. Notably, compound 2 also can be obtained in a higher yield with 1 as one of the starting material and the driving force for this transition process was carefully discussed.
