title: Stepwise nucleophilic substitution of manganocene, syntheses and structures of the dimer [CpMn(hpp)]2 and the unusual manganate cage [LiMn(hpp)3]2 (hppH = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2,a]pyrimidine).
abstract: While the nucleophilic substitution reaction of manganocene [Cp(2)Mn] with Li(hpp) (1 : 1 equivalents) gives the neutral dimer [CpMn(hpp)]2 (1), further substitution of the Cp ligands leads to the unusual dimeric manganate cage compound [LiMn(hpp)3]2 (2), generated by the dimerisation of a simple tris-organomanganate monomer.
