We used the spin-Hamiltonian method for the analysis of the electron paramagnetic resonance (EPR) spectrum of Fe 3+ asa probe ion in (NH4)2AIF 5. H20 single crystalline basic material. The theoretical expressions for the magnetic field (at which the fine structure transition lines appear) versus the angle between the magnetic field and the axis of symmetry of the magnetic complex are also given. These values were calculated by applying the perturbation theory to the second-order terms.

“…A compound with the empirical formula PdF 3 was originally proposed to contain Pd(III) [16,17], but was subsequently shown to by more appropriately formulated as Pd 2+ [PdF 6 ] 2− and contain Pd(II) and Pd(IV) [18,19]. The polyatomic anions PdF 4 − and PdF 6 3− have been prepared by solid-state synthesis [20-22].…”

While the organometallic chemistry of Pd in its (0), (+II), and (+IV) oxidation states is wellestablished, organometallic Pd(III) chemistry remains widely unexplored. Few characterized Pd(III) complexes are known, which has inhibited detailed study of the organometallic chemistry of Pd(III). In this review, the potential roles of both mono-and dinuclear Pd(III) complexes in organometallic chemistry will be discussed. While not widely recognized, Pd in the (+III) oxidation state may play a significant role in a variety of known Pd-catalyzed reactions.

Analysis of Charge-Orbital Ordering in Compoundswith Mixed Valence BY G. V. IONOVA (a) , E. P. MAHAROV (b), 0. M. PACHEV (b), and 5. P. IONOV (c) Orbital and charge ordering in transition element compounds are considered and a theoretical model is established. Special emphasis is given to the divalent compounds of Cu2+, Ag2', Au2+ and the trivalent compounds of Pd3+ and Pt3+. It is shown that spatial orbital ordering takes place in cornpounds with strong intracentre correlations (Cut+, &2+, Mn3+) and that strong intercentre correlation results in charge ordering on orbitals or centres (Ag2+, Au2+, Pd3+, and Pt3+). Real systems and lattice distortions caused by spatial and charge ordering are discussed.
