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 M4S[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. [ABSTRACT FROM AUTHOR]
