One of the six-membered rings adopts a screw-boat conformation, one adopts an envelope conformation and the third is planar. O hydrogen bonds connect the diruthenium units into a chain. The title compound is isostructural with the chloro compound. The present study includes the determination of the H-atom parameters, which revealed a strong asymmetric hydrogen bond with an O.
O hydrogen bond, forming chains extended in the a-axis direction. N hydrogen bonds together with weak N.
The are two molecules in the asymmetric unit. N hydrogen bonds together with weak N.
O hydrogen bonds, linking the independent molecules into dimers, may be effective in the stabilization of the crystal structure.
bridging and terminal.
O hydrogen-bonding interactions link the molecules in the crystal structure, forming two-dimensional layers. The sandine framework consists of two five- and three six-membered condensed rings. N hydrogen-bonding interactions which give rise to dimers in the solid state.
There is a centre of symmetry at the mid-point of the Pr.
This conformational flexibility may well reflect the influence of crystal packing on the molecular structure.
