The copper(i) metal azolate framework showing unusual coordination mode for the 1,2,4-triazole derivative and photocatalytic activity†
Abstract
A unique three-dimensional metal azolate framework containing a tetranuclear copper cluster constructed by six 1,2,4-triazole units was synthesized in which the 1,2,4-triazole units show unusual bridging “crevice” coordination mode with their 1- and 2-positioned sp2 N-atoms as symmetrically bridging centers. The photocatalytic activities of as-prepared compound were tested by degradation of rhodamine-B (RB) under different light irradiation.
