Abstract

In the title compound, [RuCl(2)(C(4)H(4)N(2))(4)]·2CH(2)Cl(2), the Ru(II) atom occupies a position of 222 symmetry and the C atom of the solvent mol-ecule occupies a site with twofold symmetry. The Ru(II) atom has a slightly distorted octa-hedral geometry. The pyrazine rings are propeller-like and rotated 45.1 (1)° from the RuN(4) plane. In the crystal, the complex and solvent mol-ecules are bridged by weak C-H⋯N hydrogen bonds along the c axis. Weak inter-molecular C-H⋯Cl contacts link the complexes in the ab plane, forming a network.
