Insights into supramolecular design 2: Analysis of anion coordination geometry of oxoanions in a protonated polyamine matrixPart 1: ref. 1. Electronic supplementary information (ESI) available: Hydrogen bonds for new compounds. See http://www.rsc.org/suppdata/ce/b1/b109449a/

Abstract

Single-crystal X-ray diffraction analysis of 16 hydrogen bonded structures formed from reaction of 8 aliphatic polyamines with nitric (1), phosphoric (2) and sulfuric acid (3) is reported. The polyamines included are diethylenetriamine, and 2,2',2@-triaminotriethylamine, N[(CH 2 ) 2 NH 2 ] 3 (h). The complexes are formed in amine : anion ratios of 1 : 1 to 1 : 4. The oxoanions are connected by hydrogen bonds to the protonated amines following specific patterns. These patterns depend on the mode of covalent connectivity of the oxygen within the anion as well as on the distance between the oxygen of interest and the central atom of the anionic species. {Part 1: ref. 1.

Triethylenetetraminium(4+) bis(sulfate) monohydrate

“…The triethylenetetraammonium cation has been crystallographically authenticated in salts of some mineral acids. It forms a dihydrate with sulfuric acid when the parent amine is reacted with sulfuric acid (Ilioudis et al, 2002). The title monohydrate, (I) ( Fig.…”

Crystal structure of bis(2-aminoanilinium) hydrogen phosphate

“…It is interesting to observe that most of the reported structures of hydrogen phosphate salts are hydrated (33 structures) compared to the reported structures of dihydrogen phosphate and phosphate salts. Most of the hydrogen phosphate structures reported contain alkyl cations (Ilioudis et al, 2002;Mrad et al, 2012;Li et al, 2010), in which the alkyl cations encapsulated between chains of hydrogen phosphate are flexible with respect to the nature of the cations, which may induce a change in physical properties (Baouab & Jouini, 1998). As observed in the title compound, in the crystal structure of 2-aminoanilinium dihydrogen phosphate (CSD refcode: SAYWAQ; Trojette et al, 1998), the dihydrogen phosphate anions form chains, which are bridged by 2-aminoanilinium cations through N-HÁ Á ÁO hydrogen bonds, generating a two-dimensional inorganic-organic network.…”
