Nickel-Boron 'Hybrid' Clusters. Synthesis of Polyhedral Nickelaboranes and Nickelacarboranes from Small Borane and Carborane Anions. Crystal Structure of (n5-C5H5)4Ni4B4H4.

Abstract

Insertion of two to four nickel atoms into polyborane cages has been accomplished by reactions of metal reagents with the B5H8(-) and (CH3)2C2B4H5(-) ions in tetrahydrofuran followed by air oxidation. Treatment of NaB5H8 with NiBr2 and NaC5H5 generates closo-1,6-(Eta 5-C5H5)2Ni2B8H8 and closo-1,7-(Eta 5-C5H5)2Ni2B10H10, and the reaction of NaB5H8 with (Eta 5-C5H5)2Ni and sodium amalgam gives closo-(Eta 5-C5H5)4Ni4B4H4 and nido-(Eta 5-C5H5)4Ni4B5H5. Nickelocene and Na (CH3)2C2B4H5 yield closo-(Eta 5-C5H5)2Ni2(CH3)2C2B4H4 and nido-(Eta 5-C5H5)2Ni2(CH3)2C2B5H5. The new compounds were structurally characterized from their (11)B and (1)H pulse Fourier transform NMR, ir, and low-and-high-resolution mass spectra, and an X-ray crystal structure determination on (Eta 5-C5H5)4Ni4B4H4.
