Crystal structure of a Zn complex with tereph­thalate and 1,6-bis­(1,2,4-triazol-1-yl)hexa­ne

A new zinc coordination polymer with rigid benzene-1,4-di­carboxyl­ate (bdc) and flexible 1,6-bis­(1,2,4-triazol-1-yl)hexane (btrh), namely poly[[(μ(2)-benzene-1,4-di­carboxyl­ato)[μ(2)-1,6-bis­(1,2,4-triazol-1-yl)hexa­ne]zinc] di­methyl­form­amide 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 di­methyl­formamide solvent mol­ecule 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 inter­molecular C—H⋯π contact of 3.07 Å occurs.
