【Abstract】 This paper deals with the reaction of B_nH_n^2-（n=9, 10 or 12 ）and B₃H₈^- with C₅H₅FeC₅H₄CH₂,N（H）Me₂Cl and Fe [C₅H₄CH₂N（H）Me₂Cl], in aquious solution to give a series of new eompounds in good yield. C₅H₅FeC₅H₄CH₂N（H） Me₂B₃H₈ can be prepared from the reaction of B₃H₈^-With C₅H₅FeC₅H₄CH₂ N（H）Me,Cl. It is an unstable compound and degrades step by step into C₅H₅FeC₅H₄CH₂NMe₂.BH₂. The products obtainded from the reaction of B₉H₉^2- or B₁₁ H₁₄ with C₅H₅FeC₅H₄CH₂N（H）Me₂ Cl also undergo degradation reaction The final products are C₅H₅FeC₅H₄CH₂NMe₂. BH₃. The Crystal of [C₅H₅FeC₅H₄N（H）Me₂]₂ B₁₂H₁₂ is Orthorhombic belonging to the space group Pcnb with a=12.975±（26）, b=16.342±（28）, c=17.582±（48）, α=β=γ=90°, V=3728³, Z=4. The structure has been so-lved and refined to R factor of 0.0588 for 1674 independent intensities grea-ter than an（Ⅰ）. [C₅H₅FeC₅H₄CH₂N（H）Me₂]₂B₁₂H₁₂ is also an ionic compound. The anions B₁₂H₁₂^2- are cations [C₅H₅FeC₅H₄CH₂N（H）Me₂]⁺ are of the dis-torted l^exahedral co-ordination and of distorted tetragonal co-ordination res-pectively. The cyclopendienoic rings are plane regular pentagonal and the planes of two cyclopendienoic rings are approximately paralled. The dihedral angle between them is 4.4°. The average bond lengths are as follows Fe—C=2.053±（4）, C—C（RING）=1.369±（7） and 1.409±（5）. The anion B₁₂H₁₂^2- is icosahedron with an average bond length B—B=1.786q±（6）.更多还原
