A number of new solvates and adducts containing bisphenyldimethylaminophosphine oxide is reported. The solvates have the general formula M[(C6H5)2P(O)N(CH3)2]42+(anion-)2, in which M = Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn and Cd, and the anions are ClO4- and BF4-. The adducts have the general formula M[(C6H5)2P(O)N(CH3)2]2Cl2, where M stands for the same series of metals.The compounds are characterized and identified by chemical analyses and physical measurements.Ligand-field and vibrational spectra have been investigated; values for the ligand-field parameters are reported. It is concluded that coordination takes place via the oxygen atom of the ligand.X-ray powder patterns were used in combination with ligand-field spectra to deduce the coordination around the metal ions.The interesting behaviour of the nickel (II) chloride adduct upon heating is discussed and it is shown that both a square pyramidal and a tetrahedral modification exists.

Ligand Field Spectra

The visible spectra of trinuclear chromium(III) acetates [Cr3O(CH3CO2)6R2]+ can be successfully analysed by means of the ligand field theory for tetragonal fields. The ligands R (R = H2O, NH3, py, DMSO) are relatively labile and may be replaced by several ligands of varying donor strength. The spectra of trinuclear iron(III) acetates [Fe3O(CH3CO2)6R3]+ are poorly resolved but can be interpreted on the basis of a d5 configuration in octahedral fields.
