Bis[glycinium(0.5+)] perrhenate.

ABSTRACT: All the residues of the title compound, (C(2)H(5.5)NO(2))(2)[ReO(4)], are located in general crystallographic positions. The glycine mol-ecules have usual conformations [Rodrigues Matos Beja et al. (2006 ?). Acta Cryst. C62, o71-o72] with the H atom of the carboxylate group half-occupied, thus bearing a formal half-positive charge per molecule. The perrhenate anion has nearly ideal tetra-hedral geometry. A large number of strong hydrogen bonds give rise to the overall three-dimensional network. A two-dimensional network, parallel to (100), is made up of strong O-H?O hydrogen bonds with a donor acceptor distance of 2.445?(2)?Å. A large number of weaker O-H?O and N-H?O hydrogen bonds consolidates the structure into an overall three-dimensional network.
