Abstract

Data on the preparation, structure, and magnetism of the new complex [Cr₄S(O₂CCH³)⁸(H₂O)4] (BF₄)₂·H₂O are presented. The metal-sulfur M₄S core structure is similar to that found in M ₄S[S₂As(CH₃)₂]₆ (where M is cobalt or zinc) compounds and in beryllium basic acetate. However, the six-coordinate metal ions in the new Cr₄S system distinguish it from these structures. The tetranuclear chromium complex is the first example of a new structural type. Its magnetic spin S = 6 ground state, a striking example of intramolecular ferromagnetic coupling, was determined by variable-temperature magnetic susceptibility measurements. Long-range antiferromagnetic intercluster ordering was found below 170 millikelvin.
