The complex chemistry of scandium. Part 1. Preparation and properties of some scandium(III) complexes of polyamines. X-Ray crystal structures of tri(nitrato-OO′)(2,2′ : 6′,2″-terpyridyl-NNN″)scandium(III) and [1,2-bis(pyridine-α-carbaldimino)ethane-NNNN‴]-di-µ-hydroxo-di(nitrato-OO′)discandium(III) dinitrate bis(acetonitrile)

Abstract

The complexes Sc(NO3)3(terpy), Sc(NO3)3(terpy)(H2O), ScCl3(tpta), Sc(NO3)3(bpce)(H2O)2, and Sc(NO3)2(OH)(bpce) have been prepared and characterised [terpy = 2,2′ : 6′,2″-terpyridyl, tpta = 2,4,6-tris(α-pyridyl)-1,3,5-triazine, and bpce = 1,2-bis(pyridine-α-carbaldimino)ethane]. Single-crystal X-ray structure determinations show that Sc(NO3)3(terpy) is monomeric, [Sc(NO3)3(terpy)], and nine-co-ordinated, while Sc(NO3)2(OH)(bpce) is dimeric, [Sc2(NO3)2(µ-OH)2(bpca)2][NO3]2, with hydroxo-bridges, each Sc ion being eight-co-ordinated.
