Abstract: | Three zinc(II) coordination polymers {Zn(btp)(1,2-bdc)(H2O)]?·?H2O} n (1), {Zn(btp)(1,3-bdc)(H2O)]?·?1.5H2O} n (2), and {Zn(btp)(NO2-1,3-bdc)(H2O)]?·?2H2O} n (3) were synthesized by 1,3-bis(1,2,4-triazol-1-yl)propane (btp) and bis-carboxylate. Compound 1 is a thick 2-D network; 2 and 3 are undulated 2-D (4,4) networks. In 2 and 3, two adjacent networks interpenetrate to form a new 2-D double-layer network, which is sustained by hydrogen-bonding interactions. Compounds 1 and 2 reveal blue emission maximum at 351 and 403, respectively, in the solid state at room temperature. |
