Rl. Davidovich et al., CRYSTAL-STRUCTURE OF THE ORTHORHOMBIC MODIFICATION OF [BI(HEDTA)]CENTER-DOT-2H(2)O, Crystallography reports, 43(4), 1998, pp. 605-607
The crystal structure of alpha-[Bi(HEdta]. 2H(2)O is studied by X-ray
diffraction (R = 0.058) to elucidate the stereochemical behaviour of t
he lone electron pair in this compound. The coordination number of bis
muth is 8, The polyhedron has an irregular shape. The O(4) atom of the
protonated acetate arm is included in Bi coordination. A stereochemic
al activity of the lone electric pair determines the difference in the
Bi-O bond lengths.
