trans-Bis(acetylacetonato-O,O')(3-methylpyridine-N)nitrocobalt(III)

Investigation of nitro–nitrito photoisomerization: crystal structures of trans-bis(acetylacetonato-O,O′)(pyridine/4-methylpyridine/3-hydroxypridine)nitrocobalt(III)

“…In the present study, the crystal structures of (I)-(III) have been determined to reveal the differences in the circumstances of the nitro ligand. The structure of (IV) was reported previously (Miyazaki et al, 1998).…”

“…There are two entries of trans-[Co(acac) 2 (NO 2 )(X-py)] in the Cambridge Structural Database (CSD Version 5.39; Groom et al, 2016), the pyridine derivative being 3-methylpyridine (Miyazaki et al, 1998), and 4,4,5,5-tetramethyl-2-(3-pyridyl)imidazolin-1-oxyl radical (Ogita et al, 2002). Entries for the other related compounds include trans-[Co(acac) 2 (NO 2 )(2aminopyrimidine)] (Kistenmacher et al, 1978), trans-[Co(acac) 2 (NO 2 )(H 2 O)] (Englert & Strä hle, 1987), and trans-[Co(acac) 2 (4-methylpyridine) 2 ]PF 6 (Tayyari et al, 2015), for which theoretical assignments of the IR bands were presented.…”
