What is Magnetic studies on the nitrate and bromide salts of the cation di-μ-hydroxobis [di( 1, 10-phenanthroline)chromium(III) ]4+ about?

## The magnetic susceptibilities of powdered samples of di-p-hydroxobis [di(l,l O-phenanthroline)chromium(III)] (NO& * 7H,O, and the analogous bromide octahydrate salt have been determined in the temperature range 5 to 283 "K. The dimers exhibit antiferromagnetic exchange interactions with the best fits to the Van Vleck expression for exchange coupled S = 312 ions including biquadratic exchange yielding, for the nitrate salt, g = I.98 f 0.03, 2J = -42.2 + 0.5 cm-', and j =Ocm-' and for the bromide salt, g = 1.95 + 0.03, 2J = -29.2 \* 0.6 cm-', and j = 0.5 + 0.1 cm-'.
