Abstract
A new zinc coordination polymer with rigid benzene-1,4-di-carboxyl-ate (bdc) and flexible 1,6-bis-(1,2,4-triazol-1-yl)hexane (btrh), namely poly[[(μ(2)-benzene-1,4-di-carboxyl-ato)[μ(2)-1,6-bis-(1,2,4-triazol-1-yl)hexa-ne]zinc] di-methyl-form-amide monosolvate], [Zn(C(8)H(4)O(4))(C(10)H(16)N(6))]·C(3)H(7)NO, was synthesized. According to the single-crystal XRD analysis, the product crystallizes in the P-1 space group and has a layered structure. Analysis of the layered structure reveals {Zn(bdc)} chains which are connected by pairs of btrh ligands. The layers are packed tightly perpendicular to the [1-22] direction, separated by one non-disordered di-methyl-formamide solvent mol-ecule per formula unit. According to thermogravimetric analysis, the product completely loses this solvent at 453 K; the desolvated compound is stable up to 503 K. As a result of the lack of hydrogen-donor groups, hydrogen bonds are not observed in the structure of the complex; however, an inter-molecular C-H⋯π contact of 3.07 Å occurs.
