Bis{2-[bis-(3,5-dimethyl-1H-pyrazol-1-yl-κN(2))meth-yl]pyridine-κN}cobalt(II) dinitrate.
The central Co(II) ion in the title complex, [Co(C(16)H(19)N(5))(2)](NO(3))(2), is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination sphere. It is bonded to six N atoms from two 2-[bis-(3,5-dimethyl-1H-pyrazol-1-yl)meth-yl]pyridine ligands. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions.
