Vv. Volkov et al., SYNTHESIS AND PROPERTIES OF THE DISSYMMETRICAL DINUCLEAR COMPLEX OF COBALT(III) WITH O-CARBORANE(12) DERIVATIVES, Russian chemical bulletin, 42(5), 1993, pp. 934-937
Dinuclear dicobaltacarborane with three different carborane fragments,
[(C2B9H11)Co(C2B8H10)Co(C2B8H10)]2-, has been synthesized, and its pr
operties have been studied by means of DTA and IR, UV, H-1 and B-11 NM
R spectroscopy techniques. It has been found that at 138-degrees-C thi
s complex undergoes thermal isomerization associated with the migratio
n of a carbon atom in the (CoC2B8H10)+ fragment to a position with a l
ower coordination number.
