A Triangle of Ba ions capped by two μ 3 ‐OSiPh 3 ligands and further linked by three μ 2 ‐OSiPh 3 moieties are present in the central structural unit of the title compound. All three Ba ions are, however, differently coordinated: thus, a terminal siloxido ligand on Ba3 caters for electrical neutrality, whereas a THF ligand is bound to Ba 1. This unusual trinuclear complex is formed in 77% yield on passage of NH 3 into a reaction mixture granulated Ba and Ph 3 SiOH in THF.
