Abstract

Manganocene, Cp2Mn, has been employed as a precursor in the synthesis of a range of Mn(II) dimers of the type [CpMn(μ-X)]2 [X = 8-NHC9H6N (1), N(Ph)(C5H4N) (2), N(4-EtC6H4)(C5H4N) (3) and C[triple bond, length as m-dash]CPh (4)] as well as the bis-adduct [Cp2Mn{HN[double bond, length as m-dash]C(NMe2)2}2] (5). The solid-state structures of 15 are reported. Variable-temperature magnetic measurements have been used to assess the extent of Mn(μ-X)Mn communication within the dimers of 14 as a function of the bridging ligands (X).
