Eight-co-ordination. Part V. Tetracyanotetrakis(alkyl isocyano)-molybdenum(IV) and -tungsten(IV) : pseudo-cubic complexes
Abstract
The diamagnetic, nonelectrolytic complexes M(CN)4(CNR)4(M = Mo or W; R = Me, Et, Prn, Pri, But, or CPh3) give unexpectedly simple i.r. and Raman spectra in the C–N stretching region. On the basis of X-ray data for Mo(CN)4(CNMe)4, all the complexes are presumed to have dodecahedral configurations.
