Rl. Davidovich et al., Crystal structure of lithium di(thiourea)ethylenediaminetetraacetatobismuthate(III) hydrate LiBi(Edta)(Tu)(2) center dot 5.5H(2)O, RUSS J IN C, 46(8), 2001, pp. 1164-1171
The mixed-ligand Bi(III) complexonate with the ethylenediaminetetraacetate
anion and thiourea molecules LiBi(Edta)(Tu)(2) . 5.5H(2)O was synthesized.
The crystal structure of this compound was determined; it consists of Li(H2
O)(4)(+) cations, intricate complex anions [Bi(Edta)(Tu)(2)-Li(H2O)(2)-Bi(E
dta)(Tu)(2)](-) (formed by linking two Bi(Edta)(Tu)(2)(-) complexes through
the Li(H2O)(2)(+) cation), and crystal water molecules. The system of N-H
. . .O and O-H . . .O hydrogen bonds combines the structural units into a t
hree-dimensional framework.
