Tris(2-ammonioethyl)amine tris({2-[(2,6-dichlorophenyl)amino]phenyl}acetate) hexahydrate

Abstract

The structure of the title compound, C 6 H 21 N 4 3+ Á3C 14 H 10-Cl 2 NO 2 À Á6H 2 O, comprises the 1:3 organic salt of tris(2ethylamine)amine and diclofenac acid, with an approximated six water molecules in an extensive hydrogen-bonding network. Two water molecules exist as full-occupancy molecules but the remainder are all disordered with partial occupancies. Disorder is also present in the base molecule, with the ammonium group of one 2-ammonioethyl arm unequally disordered over two sites.

Anion Binding by Protonated Forms of the Tripodal Ligand Tren

“…It was also observed in the presence of other oxoanions, such as HPO 4 2− , H 2 PO 4 − , SO 4 2− , MoO 4 2− , ClO 4 − , cyclohexaphosphate, and halogenides (Cl − , Br − , I − ). The same arrangement of H 3 L 3+ was also found with organic anions . In particular, with 2-(2,6-dichlorophenyl)amino)phenyl)acetate, the ligand assumes both binding modes depicted in Figure for TsO − .…”

New diclofenac salts with the dense hydrogen bond donor propane-1,3-diaminium

“…For example, Lynch and co-workers reported the 3 : 1 organic salt of dcfn with triprotonated tris(2-ethylamine)amine. 18 Here, we present several new solvatomorphic 2 : 1 salts of dcfn and propane-1,3-diaminium (Fig. 1) and the investigation of their structures and selected properties.…”
