Racemic 3,7-bis(methoxycarbonyl)-5-methylidenetricyclo[5.3.1.13,9]dodecane-2,8-dione (Yue et al., 1997) (1.00 g, 3.24 mmol) was ground into a fine powder and then a small volume of hydrazine hydrate added. After stirring the mixture for 30 min, the resulting solid was filtered, washed with a small amount of diethyl ether and dried. The creamy material was recrystallized from methanol to give shiny crystals of the dipyrazole product (0.60 g, 68%), m.p. 335–343°C (decomp.). Found: C 61.90, H 6.24, N 20.97; C15H16N4O2.H2O requires C 61.75, H 5.93, N 20.58%. X-ray quality crystals were obtained from a methanol solution of (I).
Hydrogen atoms attached to C and N were included at calculated positions (C—H, N—H = 1.0 Å). The water hydrogen atoms were located on a difference map, and then positioned with O—H = 1.0 Å. All hydrogen atoms were refined with isotropic thermal parameters equivalent to those of the atom to which they were bonded. A small number of reflections were omitted from the
due to rounding differences between the data processing and programs.Data collection: CAD-4 (Schagen et al., 1989); cell

The structural core of the title compound (I) is the rare tricyclo[5.3.1.13,9]dodecane ring system, the chemistry of which has been described by us earlier (Yue et al. 1997, 2000, 2007; Chan et al. 2008). Compound (I), Fig. 1, forms hydrogen bonded layers that lie in the (1 - 2 1) plane, Fig. 2 & Table 1. There are three motifs, all of which are centrosymmetric, which repeat within the layer. The first of these incorporates pairs of N—H···O=C hydrogen bonds. The second and third alternate along a, one comprising cycles of O—H···O=C hydrogen bonds and involving the lattice water molecules, and the other including N—H···O (water) interactions as well. In Etter's notation, the three cycles can be described as R22(8), R42(8) and R44(12), respectively (Etter, 1990).
