abstract Two new Co(II) complexes, namely [Co-2(L1)(TBIP)center dot H2O](n)(1) and [Co-2(L2)(NPTA) H2O](n) (2) (L1 = 1,4-bis(thiabendazole-1-ylmethyl)benzene, L2 = 1,2-bis(thiabendazole-1-ylmethyl)benzene, H2TBIP = 5-tert-butylisophthalic acid, and H(2)NPTA = 2-nitroterephthalic acid), were hydrothermally synthesized and characterized. 1 shows a 1D double chain, while 2 displays a binuclear structure. 1 and 2 extend into a 2D supramolecular network via C-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonding interactions, respectively. 1 and 2 exhibit excellent chemical stability in a wide pH range of 3-12. Furthermore, 1 and 2 are promising di-functional sensors for the detection of Fe3+/Cr2O72- (pH = 4) and Ni2+/MnO4- (pH = 9), respectively, with high sensitivity and selectivity and a low limit of detection.
