Abstract

The preparation, structures, and spectroscopic properties of several molecular complexes and a one dimensional chain are described. A one-dimensional { trans -Cr II (DMF) 2 (OTs) 2 } n (1) chain and mononuclear complexes of trans -[M II (OTs) 2 (DMF) 4 ] (M II = Fe, 2; Co, 3) and [Ni II (DMF) 6 ][OTs] 2 (4) stoichiometry are readily obtained from DMF/Et 2 O solutions containing the parent anhydrous tosylate salts. A hydrated analogue, trans -[Fe II (OTs) 2 (OH 2 ) 2 (DMF) 2 ] (5), is obtained in minor quantities from solutions containing 2. Electronic spectra indicate all of the complexes adopt octahedral geometries in dimethylformamide solution. Room temperature susceptibility data indicates that high spin electronic configurations are preferred for 1 ( S = 2), 2 ( S = 2), and 3 ( S = 3 / 2 ) while 4 adopts an S = 1 spin ground state. The solubility properties of the salts are also described.
