Tris(salicylaldehydato)chromium(111) reacts readily with primary amines or ammonia to give complexes of the form Cr(sal-NR)3 where R = n-C3H9, i-C4H9, p-C6H4CH3, p-C6H4Br. The complexes are monomeric in benzene, and have magnetic moments in the range 3.77-3.81 B.M. at room temperature. Crystal field splitting energies have been obtained for the complexes from their spectra. Ethylenediamine reacts with the salicylaldehyde complex to give a cationic complex containing the tridentate ligand -0-C6H4-CH=NCH2CH2-NH2.

Abstract Extensive paramagnetic susceptibility studies between liquid helium and room temperature have been carried out on polycrystalline samples of the two organometallic Np(IV)-complexes Np(C5H5)4 and (C5H5)3NpCl. From a combined interpretation of the corresponding 1/Xm-vs-T-and μ2eff-vs-T-curves, respectively, is suggested that, in accordance with the tetrahedral molecular symmetry to be assumed for Xp(C5H5)4, a cubic Τ8 crystal field level should lie lowest in this compound. The zero field splitting is apparentlv smaller th an 5 cm-1.

We have extended the low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 600 p.p.m. manganese from magnetic fields of 9 to 56 kG. The crystal field splitting parameters determined at low magnetic fields also characterizes the magnetic anisotropy at high magnetic fields. Manganese–manganese interaction effects are observed in the magnetic anisotropy at manganese concentrations greater than 300 p.p.m. Low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 164 p.p.m. chromium are reported and indicate a crystal field splitting of 0.16 K for the chromium ion.
