Crystal structure of a dinuclear nitrido-bridged ruthenium complex with pyridine ligands

A new dinuclear nitrido-bridged ruthenium complex with pyridine ligands ([PyH][Ru2N(Py)4Cl6] (1) is synthesized by reacting K3[Ru2NCl8(H2O)2] (2) and excessive pyridine, then crystallized from dilute hydrochloric acid. Its crystal structure is determined by single crystal X-ray diffraction. The complex crystallizes in the form of red block crystals of the monoclinic symmetry and the space group C 2. The nitrido-bridged ruthenium complex has very short Ru–N distances.
