Structure and Photocatalytic Properties of a 3D Zinc(II) Triazolate Coordination Polymer Combining Hydroxyl and Formate Anions as the Auxiliary Coligands

A new 3D zinc coordination polymer, namely {[Zn4(dmtz)3(OH)3(HCOO)](NO3)}n (1, Hdmtz = 3,5- dimethyl-1,2,4-triazole), is hydrothermally synthesized and structurally characterized by elemental analyses, IR spectroscopy, and single crystal X-ray diffraction analysis. The complex features a (3,4,5)- connected 3D cation framework constructed by μ3-bridging dmtz with hydroxyl and formate anions as the auxiliary ligands. Moreover, the photocatalytic properties of 1 are also investigated.
