Abstract
In aqueous HBr solution (58% w/w), 1,3,5-triaza-7-phosphaadamantane (PTA) yielded the hitherto unknown triprotonated PTA, as single crystals. In addition, the same reaction mixture deposited crystals of [O = P(CH2NH3)3]Br3 (2), formed presumably by ring opening of [PTA-H3]Br3 (3) and oxidation of the resulting [P(CH2NH3)3]Br3 (1). The solid state structure of 2 and 3 were determined by X-ray diffraction. In water/methanol mixtures, reaction of 1 and [{(η6-C10H14)RuBr2}2] yielded the half-sandwich [(η6-C10H14)RuBr2{P(CH2NH3)3}]Br3 (4) which –in aqueous solution– spontaneously afforded the dinuclear [(η6-C10H14)RuBr2{μ4-P(CH2NH2)3}Ru(η6-C10H14)]Br2 (5).
