The 1,2-diaza-4-phospholide (dp) dipotassium ate complexes of chromium(ii) {[(η-N-3,5-tBudp)Cr][(η-(N,N,C,C,P))-K(η-O-THF)]} (5) and {[(η-N-3,5-Phdp)Cr][(η-(N,N,C,C,P))-K(η-O-THF)]} (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).
