N2 - The central tellurium atom coordinated to three manganese atoms in the compound (υ3-Te)[(η5-C5H5)Mn(CO)2]3 (1) exhibits electrophilic reactivity, thus undergoing methylation with methyllithium to yield the anion [(μ3-TeCH3){;(η5-C5H5)Mn(CO)2};3]-, whose structure was determined crystallographically. While the precursor compound 1 contains a planar Mn3Te core structure (d(Mn-Te) 248.7 pm, av.), carbanion addition effects pyramidalization of this fragment (d(Mn-Te) 257.7 pm, av.), with the tellurium atom appearing at a distance of 56 pm above the plane defined by the three manganese atoms.
