Rl. Davidovich et al., Ethylenediammonium ethylenediaminetetraacetatobismuthate(III) hexahydrate:Synthesis and crystal structure, RUSS J IN C, 46(1), 2001, pp. 65-68
Bismuth(III) ethylenediaminetetraacetate hexahydrate with protonated ethyle
nediamine as a counterion ({H(2)En}[Bi(Edta)(H2O)](2). 4H(2)O) was synthesi
zed; its crystal structure was determined. The complex {H(2)En}[Bi(Edta)(H2
O)](2). 4H(2)O is isostructural to its antimony analogue. The behavior of t
he lone electron pair of the Sb3+ and Bi3+ cations in the isostructural com
plexes is discussed.
