abstract
A novel 2-D heterometallic polymer [Cu-4(biimpy)(4)(V4O12)](n)center dot 2H(2)O(1, biimpy = 2,6-bis(1-imdazoly) pyridine) has been hydrothermally synthesized and structurally characterized. 1 contains a rare 2-D heterometallic biimply layer built up from the linkages of the circle [V4O12](4-) clusters and two types of 1-D cuprous polymeric chains. Although a few cuprous imidazolate derivatives have been reported, their extended structures are generally constructed by only one type of building units. Therefore, 1 provides the rare example of 2-D layer based on two types of building units, namely 1-D cuprous polymeric chains and circle [V4O12](4-) clusters. 1 displays selectively photocatalytic of methylene blue under visible light irradiation. Spectroscopic properties and density functional theory calculation of 1 have been also investigated. (C) 2017 Elsevier B.V. All rights reserved.
