Abstract
Solvothermal reactions of Zn(NO3)2·6H2O, H3tci, and biimpy generated a new ZnII coordination polymer namely [Zn3(tci)2(biimpy)]n·2n(DMF) (1 H3tci = tri(2-carboxyethyl)isocyanurate, biimpy = 2,6-bis(1-imdazoly)pyridine, DMF = N,N-dimethylformamide). Single-Crystal X-ray diffraction analysis reveals that compound 1 features a 2-fold interpenetrated 3D pillar-layered framework based on trinuclear [Zn3(COO)6] cluster subunits. Topological analysis reveals that compound 1 represents a 2-fold interpenetrated (3,8)-connected tfz-d topological network with the point symbol of {43}2{46.618.84}. The luminescence properties of compound 1 dispersed in different organic solvents were systematically investigated. The results indicated that compound 1 can be used as a candidate for selective sensing of CCl4 via a luminescence quenching mechanism.
