Redetermination of triethylammonium chloride in the space group P31c.
The structure of triethylammonium chloride has been reported four times to date (Hendricks, 1928; Genet, 1965; James et al., 1985; Ilyukhin, 2000). All four structure determinations were made in the space group P63mc (No. 186) and showed `propeller'-like disorder of the cation (Fig. 1) caused by a crystallographic mirror plane. Two closely related models were used in the later re®nements. In th...
متن کاملDisposition in rats of N-pyridinium-propyl-cyclam, N-triethylammonium-propyl-cyclam, and N-[Triethylammonium]-3-propyl-[15]ane-N5, potential cartilage imaging agents.
Quaternary ammonium compounds are known to highly concentrate in articular cartilages after i.v. administration. This property was used to synthesize new potential radiodiagnostic agents for joint imaging. Pharmacokinetic study was performed in rats for three new compounds: N-pyridinium-propyl-cyclam (NPPC), N-triethylammonium-propyl-cyclam (NTPC), and N-[triethylammonium]-3-propyl-[15]ane-N5 (...
متن کاملReactions of (benzamidomethyl)triethylammonium chloride with some inorganic nucleophiles in aqueous media.
A variety of benzamidomethyl derivatives were prepared in water under alkaline conditions (pH>9) via reaction of (benzamidomethyl)triethylammonium chloride (1) with different inorganic nucleophiles. Reaction of 1 with hydroxylamine did not give the expected mono(benzamidomethyl)-hydroxylamine (3) but rather gave N,N- di(benzamidomethyl)hydroxylamine (2). Reactions of 1 with sodium azide and pot...
متن کاملThe case of triethylammonium cation loss during purification of certain nucleotide analogues: a cautionary note
Nucleotides, their analogues, and other phosphate esters and phosphoramidates often contain the triethylammonium cation as a counterion. We found that this may be lost during chromatographic purification or concentration of solutions, yielding products in acidic forms or containing sub-stoichiometric amounts of the counterion. This in turn may be detrimental, e.g., due to possible decomposition...
متن کاملCrystal Structure of Bis(triethylammonium)c/0so-decahydrodecaborate, [(C2H5)3NH]2[B10H10]
The crystal structure of bis(triethylammonium)c/o5o-decahydrodecaborate [bis(triethylammonium)decaboranate(lO)], [(CaHs^NHMBioHio], was determined and refined (space group Pmmn, no. 59, a = 989.7, b = 1333.7, c = 903.7 pm). The compound is a versatile starting material for many substances containing the [BioHio]2entity and its derivatives. The c7oso-[BioHio]2cluster is a bicapped square antipri...
