Abstract
Hydrothermal reactions of aromatic terphenyl-4,2′′,5′′,4′-tetracarboxylic acid (H4tta) and transitional metal salt Co(NO3)2·6H2O in the presence of flexible N-donor ancillary ligand afforded two novel coordination polymers, namely, {[Co(tta)0.5(m-bimb)]·H2O} n (1) and [Co2(tta)(m-bimb)2(H2O)] n (2), from solvothermal reactions in the presence of bis(imidazole) bridging linkers (m-bimb = 1,3-bis(imidazol-1-ylmethyl)benzene). The structural characterization results show that complex 1 features a 3D framework structure with a 2-fold interpenetrated (4,4)-connected bbf net, while complex 2 shows a 3D non-interpenetrated network with a novel (4,8)-connected net with the Point Symbol of (32·53·6)(34·44·59·611). Their treatment and nursing values on acute renal failure during pregnancy was evaluated and the related mechanism was explored at the same time. First of all, the content of the 24-hour urine protein was measured to determine the protective activity of the compound on kidney function. Next, the relative expression levels of the aquaporin on renal tubular endothelial cells were measured with real time RT-PCR.
