- Abstract
- A new dodecanuclear Bi(III) complex with 2-hydroxy-1,3-diaminopropanetetraacetic acid (H(5)hpdta) corresponding to the stoichiometry Bi-12(Bi(12)hdtpa)(4)(Hhdtpa)(6) was obtained from Bi(III) oxocarbonate and the starting polyaminocarboxylic acid. The crystal structure revealed the presence of two asymmetric parts containing six Bi atoms, each of which displays a ninefold coordination. The involvement of the central hydroxo group in Bi coordination is assumed to be responsible for the peculiarities of this unique structure: the simultaneous involvement of one of the ligands in the coordination of two Bi atoms, the presence of Bi atoms bridged by either one, or three oxygens at the same time, the presence of bridging bidentate (mu(2):eta(1):eta(2)) carboxylates, and direct coordination of Bi(III) to water molecules.
