Va. Grillo et al., BIS(BETA-DIKETONATE) LIGANDS FOR THE SYNTHESIS OF BIMETALLIC COMPLEXES OF TI-III, V-III, MN-III AND FE-III WITH A TRIPLE-HELIX STRUCTURE, Chemical communications, (16), 1997, pp. 1561-1562
Addition of the bis(beta-diketone) ligand L [L = 1,3-bis(3-phenyl-3-ox
opropanoyl)benzene] to a suitable source of M-III ions (M = Ti, V, Mn,
Fe) in a L:M = 3:2 ratio gives the dinuclear products [M2L3], which h
ave a triple-helical structure.
