(2,2′-Bipyridine-κ2N,N′)chlorido(1,4,7-trithiacyclononane-κ3S,S′,S")ruthenium(II) nitrate monohydrate

In the title compound, [RuCl(C10H8N2)(C6H12S3)]NO3 center dot H2O or [RuCl(bpy)([9]aneS(3))]NO3 center dot H2O, ([9]aneS(3) is 1,4,7-trithiacyclononane and bpy is 2,2'-bipyridine), the Ru-II cation has a slightly distorted octahedral environment composed of three facially coordinated S atoms from ([9]aneS(3)), two N atoms from bpy and a chloride anion. The nitrate counter-ion and the water molecule of crystallization are engaged in O-H center dot center dot center dot O hydrogen-bonding interactions, leading to a supramolecular chain running parallel to the c axis.
