title: A new organically templated vanadium tellurite: (H2dien)[(VO2)(TeO3)]2.2H2O (dien is diethylenetriamine).
abstract: A new organically templated vanadium tellurite, poly[2,2'-iminodiethanaminium [hexa-mu2-oxido-tetraoxidoditellurium(IV)divanadium(V)] dihydrate], {(C4H15N3)[Te2V2O10].2H2O}n, features the interconnection of distorted [VO5] trigonal bipyramids by bridging [TeO3] pyramids, leading to a two-dimensional corrugated anionic layer with an interlayer distance of about 13.47 A. The interlayer space is occupied by doubly protonated diethylenetriamine cations (H2dien) and guest water molecules. The two terminal amino groups of H2dien are protonated, while the middle amino group, located on a twofold rotation axis, is not protonated. All the three amino groups and water molecules are involved in hydrogen-bonding interactions. The compound represents a new member in the series (H2am)[(VO2)(TeO3)]2.xH2O, where H2am represents a doubly protonated diamine. Similarities and differences between the structures of members of the series are discussed.
