Ts. Knowles et al., IMPROVED SYNTHETIC ROUTES TO TRIS(ACETYLACETONATO)RUTHENIUM(III) AND A REDETERMINATION OF THE STRUCTURE OF THE BETA-POLYMORPH, Polyhedron, 13(14), 1994, pp. 2197-2203
The ruthenium-blue cluster-mediated synthesis of Ru(dike)3 complexes (
dike = beta-diketone) has been investigated in view of the low yields
this route usually produces. Only the acetylacetonato complex of the m
etal was isolated without modifications to the procedure, allowing a r
edetermination of the crystal structure to be carried out, previously
published data relating to the structure of the racemic complex is inc
orrect and is now superseded by a more accurate determination. Two for
ms of this complex have now been isolated, and a comparative analysis
of these is presented here.
