Abstract
The Grignard analogue (2) and the novel lithium silanolatocobaltates Li(THF)2(μ-Br)2Co(μ-OSiMe3)2Co(μ-Br)2Li(THF)2 (4) and [LiBr{Li(THF)}2{CoBr(OSiMe3)3}]2 (5) form dimeric molecules in the crystalline state. Below 200 K there are significant antiferromagnetic interactions between the cobalt centres in 4. In 5 two cubane-like fragments containing silanolato bridges are linked together through a Li2Br2 ring.
