报道了一系列六配位[Cu（L）L1][BF 4]2（L1 = 2，6-二{1-氧代-4，4，5，5-四甲基-4，5-二氢-1H-咪唑-2-基}吡啶）配合物。Cu和L1配体自旋之间的铁磁耦合被增强的L coligand与远端甲基取代基，这是由于空间诱导抑制其Jahn-Teller失真。
A series of six-coordinate [Cu(L)L1][BF4]2 (L1 = 2,6-bis{1-oxyl-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-2-yl}pyridine) complexes are reported. Ferromagnetic coupling between the Cu and L1 ligand spins is enhanced by an L coligand with distal methyl substituents, which is attributed to a sterically induced suppression of its Jahn-Teller distortion.
