An unprecedented polyborate ester anion: X-ray diffraction studies on [1,8-C10H6(NMe2)(2)H][B5O6(OMe)(4)]
The slow hydrolysis of B(OMe)(3) in a CH2Cl2 solution in the presence of 1,8-C10H6(NMe2)(2) (5:1 ratio) led to the formation of the novel isolated pentaborate ester anion [B5O6(OMe)(4)](-), which was characterized by a single-crystal X-ray diffraction study as the salt [1,8-C10H6(NMe2)(2)H][B5O6(OMe)(4)].
