摘要：
The heteroborane dianions B11H11E2- (E = Ge, Sn) have been prepared in good yield starting with the B11H14- ion, ECl2, and n-butyllithium. The B11H11Pb2- ion was made from B11H14- and PbCl2 in aqueous sodium hydroxide solution. Methylation of the respective heteroborane dianion formed the B11H11GeCH3- and B11H11SnCH3- ions in good yield. The compound [1-CH3-1-SnB11H11]PPh3CH3.CH2Cl2 has been characterized by a single-crystal X-ray structure determination (space group P1BAR, a = 11.659 (3) angstrom, b = 13.580 (3) angstrom, c = 9.980 (2) angstrom, alpha = 109.65 (1)-degrees, beta = 94.91 (1)-degrees, gamma = 99.83 (1)-degrees, Z = 2).
