The synthesis, solid-state structure, and solution structure of Cr-2(tBu(2)pz)(4) are described. This complex is obtained by sublimation of the monomeric species Cr(tBu(2)pz)(2)(4-tBupy)(2) and contains long chromium-chromium distances that are enforced by the divergent nature of the pyrazolato ligands.
