Abstract
The polarised single-crystal eletronic spectra, e.s.r. spectra, and bulk magnetic susceptibility of µ-formato-mono-(diethylenetriamine) copper(II) formate have been measured. The correlation of the single-crystal g-values and the crystallographic data suggests a dx2–y2 ground-state for the approximately square-pyramidal CuN3O2 chromophore. The room-temperature magnetic moment of 1·95 BM and a Weiss constant of θ=–5° suggest negligible antiferromagnetism. The polarised single-crystal electronic spectra are interpreted in C2v effective symmetry and yield a tentative one-electron orbital sequence dx3–y2 > dz2 > dxy > dxz > dyz. The energies of these transitions are compared with those of the corresponding transitions of other copper(II) complexes having a square-pyramidal stereochemistry.Keywords
