Correlation of electron paramagnetic resonance line intensities with magnetic moments for some spin-crossover systems

Abstract

New Route to the Preparation of

Crystal and molecular structure of [Cu(bcp)2]BF4.cntdot.CH3OH (bcp = 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline)

“…16 The dihedral angle between the mean phenanthroline planes is 87.62 (5)°, while the dihedral angles defined by the individual phenyl substituents related to the attached phenanthroline range between 39.33 (23) and 48.26 ( 16)°. By comparison, the dihedral angle between the mean plane of the phenanthroline moiety and the mean plane of the phenyl substituents is 63.17 (5)°i n the structure of the free ligand. 29 In the complex, the phenyl rings are rotated in a disrotatory sense on both ligands, possibly to facilitate stacking interactions.…”
