trans -Dichloridotetrapyrazineruthenium(II) dichloromethane disolvate

In the title compound, [RuCl2(C4H4N2)4]·2CH2Cl2, the RuII atom occupies a position of 222 symmetry and the C atom of the solvent molecule occupies a site with twofold symmetry. The RuII atom has a slightly distorted octahedral geometry. The pyrazine rings are propeller-like and rotated 45.1 (1)° from the RuN4 plane. In the crystal, the complex and solvent molecules are bridged by weak C—H...N hydrogen bonds along the c axis. Weak intermolecular C—H...Cl contacts link the complexes in the ab plane, forming a network.
