✦ Synopsis
HigIl-resolution absorption, iuminesccnce, Zeeman and MCD experiments were performed cm sir& crystals of the title compound. The singlet-tripiet and trip&t-quintet exchange splittings in the ground state are 138 and 267 cm-'. respectively. The corresponding exchange parameters are 2J= -128 cm-' andj = 1.6 cm-t let ground level is -2.25 cm-', _ The zero-field splitting in the triptotal spread of 8 cm-t.
The Iowest-energy emitting state is a 3E state, split into four spinor components with a
