Bis{2,6-bis[3-(2,4,6-trimethylphenyl)pyrazol-1-yl-N²]pyridine-N}cobalt(II) dinitrate at 290 and 150 K

Abstract: The title compound, [Co(C₂₉H₂₉N₅)₂](NO₃)₂, contains a six-coordinate high-spin Co^II ion with approximate local D_2d symmetry. The bond lengths and angles at cobalt undergo only small changes between the two temperatures, which confirms that the Co^II ion does not undergo a spin-state transition over this temperature range.

Formula: [Co(C₂₉H₂₉N₅)₂](NO₃)₂ at 290 and 150 K
