Abstract

E.s.r. spectra of the complexes MnL2Cl2(L = Ph3PO, Ph3AsO), MnL2Br2(L = Ph3PO, Ph3AsO, 3-methylisoquinoline, or quinoline), Mn(Ph3PO)2I2, and Mn(Ph3AsO)2(NCS)2 are reported at X-band and at Q-band frequencies, together with those of some of the complexes diluted in the corresponding zinc compound. The spectra are interpreted by comparison with calculated spectra, and values of the distortion parameters D and λ(=E/D) have been deduced.
