摘 要: | Quantitative reaction between copper(I) cyanide and triphenyl phosphite forms copper(I) complex (P(OPh)3)gCug(CN)4] (1). X-Ray crystal structure shows a catenarian polymer of tandem interconnected copper cyanide, with C and N connecting to proximal Cu atoms. The Cu atoms adopt two different conformations: one exhibits linear construction, while the other exhibits distorted tetrahedral geometry through coordinating to two cyano groups and the P donors of triphenyl phosphite molecules. The feature of 1 is the propagation pattern of two- and four-coordination along with the chain. IR and electronic absorption spectra also confirm the established single crystal structure. Thermal analysis indicates that 1 has a high thermal stability. 3-D fluorescence result shows the middle absorption peaks with the maximum excitement and emission wavelength 342 and 350 nm, respectively. Cyclic voltammogram in DMSO, DMF and MeCN gives a midpoint voltage of --0.003, 0.061 and 0.137 V versus SCE, respectively, showing the different solvent virtue on reduction potential.
