Construction of a New Co(II) Coordination Polymer With Excellent Photocatalytic Property

Abstract

A new Co(II) coordination polymer, namely [Co2(mbdc)(ATAZ)2(H2O)2]n·nH2O (1; H2mbdc = isophthalic acid, HATAZ = 3-amino-1,2,4-triazole) has been synthesized via the solvothermal reactions of Co(NO3)2, isophthalic acid and 3-amino-1,2,4-triazole. Single-crystal X-ray diffraction analysis reveals that compound 1 features a 3 D pillar-layer framework based on Co(II)-aminotriazole layers and mbdc2− pillars, which can be simplified into a noninterpenetrated pcu topological network. The photocatalytic studies on compound 1 indicate that it can be used as an active catalyst for the photodegradation of methylene blue under UV light.
