The room-temperature photochemical reaction of the tricarbollide anion [nido-7,8,9-C3B8H11](-) (1a) with [CpFe(C6H6)](+) proceeds without cluster rearrangement to form the 12-vertex closo-ferratricarbollide 1-Cp-1,2,3,4-FeC3B8H11 (2a, the metal atom is assigned number 1). 2a rearranges to the isomeric complex 1-Cp-1,2,3,5-FeC3B8H11 (2b) at 110 degrees C and further to 1-Cp-1,2,4,10-FeC3B8H11 (2c) at 165 degrees C. The reaction of 1a with [Cp*RuCl](4) is accompanied by polyhedral rearrangement giving 1-Cp*-1,2,3,5-RuC3B8H11 (3b). The constitution of the compounds prepared was determined by multinuclear NMR spectroscopy and mass spectrometry. The structures of 2a, 2b, and 3c were established by X-ray diffraction.

Ferra a ruthenatrikarbollidy CpFeC3B8H11 a Cp*RuC3B8H11byly připraveny insercí fragmentů CpFe+ a CpRu+ do skeletu trikarbaboranového aniontu [nido-7,8,9- C3B8H11]- . Je popsán i vznik několika isomerů lišících se polohou uhlíkových atomů ve skeletu.
