Abstract

Hexagonal FeBd3(BF)2·5CHCl3 single crystals (space group P63, a=14.975(2), c=16.301(3) Å, V=3166(1) Å3, Z=2) have been obtained by recrystallizing a preliminarily synthesized clathrochelate diphenyl- glyoximate complex. The iron atom is encapsulated by the macrobicyclic ligand and surrounded by a distorted trigonal prismatic coordination consisting of six nitrogen atoms. The distortion angle value found experimentally (c. 29.3°) is close to that estimated earlier from Mössbauer parameters (27–30°). The FeN bond length (1.91(2) Å) is characteristic of clathrochelate boron-containing iron(II) dioximates and is determined by the superposition of the contributions of metal eletron configuration and ligand geometry.
