Description
Summary:Quantitative reaction between copper(I) cyanide and triphenyl phosphite forms copper(I) complex [(P(OPh)3)4Cu4(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.
