Based on the hydrolysates of N,N′-bis(3,5-dicarboxylatophenyl)pyromelliticdi-imide) (H4L) and 1,3-bis(imidazol-1-ylmethyl)benzene (bimb), three coordination polymers, namely, {[Zn(BTC)0.5(bimb)]·4H2O}n (1), [Cu(BTC)0.5(bimb)]n (2), and {[Cd(AIP)(H2O)]·H2O}n (3), have been obtained under solvothermal conditions. The possible hydrolysis mechanism of H4L was investigated here. Structural analyses reveal that complex 1 is a 3D (4,4)-c {6⁴.8²}{6⁶}2-bbf net. Complex 2 displays a 2D 4-c {3².6².7²}-kgm sheet. While complex 3 exhibits a 3D (3,6)-c {4.6²}2{4².6¹⁰.8³}-rtl net based on binuclear {Cd2(COO)4} SBUs. Besides, luminescent sensing investigation indicated that 1 and 3 exhibit highly sensitive and selective sensing of chromate anions in aqueous solution.
