Structural architectures of charge-assisted, hydrogen-bonded, 2D layered amine center dot center dot center dot tetraphosphonate and zinc center dot center dot center dot tetraphosphonate ionic materials

摘要

The synthesis, characterization and structural analyses of ionic amine-phosphonate and hydrated metal ion-phosphonate compounds are reported. These are (en)(HDTMP), (NH4)(EDTMP), Zn(H2O)(6)(TDTMP) (en = ethylenediamine, HDTMP = hexamethylenediamine-tetrakis(methylenephosphonate), EDTMP diethylenediamine-tetrakis(methylenephosphonate), TDTMP = tetramethylenediamine-tetrakis(methylenephosphonate)). All three compounds are composed of discrete anions and cations. stabilized by intricate networks of hydrogen bonds, and form 2D layered architectures.
