摘要：

The 1,2-diaza-4-phospholide (dp(-)) dipotassium ate complexes of chromium(II) {[(eta(1)-N-3,5-tBu(2)dp)(4)Cr][(eta(5)-(N,N,C,C, P))(2)-K(eta(1)-O-THF)(2)](2)} (5) and {[(eta(1)-N-3,5-Ph(2)dp)(4)Cr][(eta(5)-(N,N,C,C,P))(2)-K(eta(1)-O-THF)(2)](2)}(infinity) (6) were synthesized and characterized by X-ray single crystal structure analysis. Complex 5 with a near-square planar geometry at the chromium(II) ion was unambiguously characterized by the high field electron paramagnetic resonance (HF-EPR) technique and magnetic measurements, revealing that it is a field-induced single-molecule magnet (SMM).
