Säure-Base-Eigenschaften des zyklischen Triamins N,N′,N″-Trimethyl-1,4,7-triazacyclononan: Die Kristallstruktur seiner monoprotonierten Form [C9H22N3]ClO4) / Acid-Base Properties of the Cyclic Triamine N,N′,N″-Trimethyl-1,4,7-triazacyclononane and Crystal Structure of its Monoprotonated Form [C9H22N3](ClO4)

Abstract

The crystal structure of the monohydroperchlorate of N,N',N"-trimethyl-1,4,7-triazacyclo-nonane, [C9H22N3](ClO4), has been determined by single crystal X-ray diffraction. The acidic proton of the cation is bonded to one amine nitrogen and it forms hydrogen bonds to the other two N-atoms in agreement with a proposed model, which has been invoked to interpret successive protonation constants of cyclic triamines. The salt [Me6[9]aneN3](BF4)3 has also been prepared
