The title compound, (C18H18N6)2[Mo8O26], was produced by hydrothermal reaction of an acidified aqueous solution of Na2MoO4 and 1,1′-bis(pyridin-4-ylmethyl)-2,2′-bi-1H-imidazole (hereafter L). The structure consists of the β-octamolybdate anions having a crystallographic center of symmetry and protonated [H2 L]2+ cations. The [H2 L]2+ cations link β-octamolybdate anions, generating a two-dimensional hydrogen-bonded supramolecular sheet.

In the title compound, C30H48BNOP2·0.5H2O, the water molecule is disordered about an inversion centre. Both phosphorus atoms shows distortions in their tetrahedral environments with the cyclohexyl substituents disordered over two orientations in a 0.851 (3):0.149 (3) occupancy ratio. The crystal structure is assembledviaO—H...O interactions between pairs of phosphininc amide molecules and water molecules, creating hydrogen-bonded dimers with graph-setR24(8) along [001]. Weak C—H...O interactions are also observed.

Dimensional Crystal

The two-dimensional crystal packing of the title compound, C3H5N4O2+·NO2−·H2O, results from the stacking of well separated layers (i.e.with nothing between the layers) parallel to the (-113) plane in which adjacent cations adopt a head-to-head arrangement such that two –COOH groups are linkedviatwo water molecules (the water O atom behaves simultaneously as donor and acceptor of hydrogen bonds) and two –NH2groups are linked through two nitrate anions. This arrangement leads to alternating hydrophilic and hydrophobic zones in which O—H...O and N—H...O hydrogen bonds, respectively, are observed.
