(3d). The ferradicarbollides 2a–e were synthesized by reactions of the charge-compensated dicarbollide anions [9-L-7,8-R2-7,8-C2B9H8]– (R = H, Me) with [(C5R5)Fe(MeCN)3]+ cations. The structures of 1, [NMe3Ph][1], and 2b were investigated by X-ray diffraction. The ME spectroscopic study elucidated the relationship between the nature of the five-membered carborane face coordinated to the metal center
