Abstract
The 2,8-dihydroxy-1,3,7,9-tetramethyl-6,12-dihydrodipyrido-[1,2-a:1',2'-d]p yrazinediylium dication possesses 2/m symmetry and lies in the mirror plane together with a chloride anion and the water O atom. The dication also lie s on an inversion centre, i.e. C16H20N2O22+. 2C(-). 2H(2)O. Due to these sy mmetry constrictions the dication adopts an unexpected planar conformation. Molecules are linked by O-H ... O and O-H ... Cl hydrogen bonds to form ch ains, which are cross-connected by C-H ... Cl attractive interactions formi ng a complex three-dimensional hydrogen-bond network.
