The reaction of MCl2 (M=Zn, Cd and Hg) with Li(2-(C(SiMe3)2)(6-Me–C5H3N)), [Li(MeR)], affords mononuclear metal(II) alkyls. These, in the solid state, show intramolecular M–N interactions in their four-membered chelate rings, which progressively

Reaction of cis-[RuCl2(PPhMe2)4] with {(TMEDA)Li}2{(2-CH2C6H4)2} yields the thermally unstable metallacycloheptadiene, [Ru{(2-CH2C6H4)2}(PPhMe2)3] (1), which in the solid has a distorted square pyramidal structure with the two ligating carbon atoms i

Hexaammineruthenium(III) trichloride forms a Z = 12 monoclinic crystal, which is related to a simple cubic f.c.c. structure by, dominantly, a rotation of a third of the hexaammineruthenium(III) fragments. The cell contains four crystallographically i
