Crystal and Molecular Structure of (3,3'-Dimethyl-2,2'-bipyridyl)methylmercury(II) Nitrate; a Complex That May Have Weak Intramolecular Pi-Coordination

The title complex, C13H15HgN3O3, has a bent C(1)-Hg-N(1) group [172,7(5)] with Hg-C(l) 2,01(1) and Hg-N(1) 2,11(1) A, weak interaction between Hg and nitrate oxygen atoms, and evidence suggesting the presence of a weak intramolecular pi-interaction between Hg and the second pyridyl ring, with Hg-C(2') 3,11(1), Hg-N(1') 3,29(1) A and an angle of 100, 5 between the planes of the pyridyl rings.
