material is unavailable. 113Cd solid‐state NMR is easy to measure and is a highly sensitive probe because the coordination number, the nature of coordinating groups, and the geometry around the metal ion is reflected by the isotropic chemical shift and the chemical‐shift anisotropy. Here, a detailed investigation of a series of 27 cadmium coordination polymers by 113Cd solid‐state NMR is reported. The results
The syntheses and crystalstructures of a mononuclear cadmium complex and five novel coordinationpolymers based on 1,2,4-triazolyl benzoates are presented. The compounds ∞3[Cd(H-Me-trz-pba)2] (2), ∞3[Cd(Me-3py-trz-pba)2] (4), and ∞3[Zn(H-Me-trz-pba)2] (6) can be obtained by solvothermal synthesis or simple heating of the starting materials in appropriate solvents, and are also accessible by thermal
