X-Ray study of the co-ordination geometry about iron in the {fluoro[6,6′,6″-phosphinidynetris(α-picolinaldehyde oximato)(3–)]borato(1–)}iron(1+) cation. Trigonal prismatic encapsulation vs. octahedral ligand-field stabilization energy

Abstract

A single crystal X-ray diffraction study of [{FB(ONCH·C5H3N)3P}FeII]+[BF4]–, CH2Cl2 shows the co-ordination geometry about the iron atom to be distorted by approximately 21·5° from the ideal trigonal primatic case.
