Abstract
The reaction between Re2(DMBA)4Cl2 and NaN(CN)2 resulted in Re2(DMBA)4(N(CN)2)2 (1a), where DMBA is N,N′-dimethylbenzamidinate. Molecular compounds Re2(DMBA)4(ReO4)2 (1b) and Re2(DMBA)4(OP(O)(OH)Ph)2 (1c) were obtained through the reactions between Re2(DMBA)4(NO3)2 and the respective monoanion. The dirhenium(III) coordination polymers [Re2(DMBA)4(μ-O,O′-WO4)·2H2O]∞ (2a), [Re2(DMBA)4(μ-O,O′-MoO4)·2H2O]∞ (2b), and [Re2(DMBA)4(μ-O,O′-1,4-(O2C)2C6H4)·2H2O]∞ (2c) were similarly prepared through slow diffusion of Re2(DMBA)4(NO3)2 in acetonitrile into aqueous solution containing the respective dianion. All new compounds were characterized with single crystal X-ray diffraction, which revealed the retention of the essential structural features of Re2(DMBA)4 unit upon the formation of coordination polymers.
