Synthesis, characterization and crystal structure of bis(acetylacetonato)dimethanolnickel(II): [Ni(acac)2(MeOH)2]

“…These are slightly longer than the values reported for the monemeric [Ni(acac) 2 ] complex [3,4], which can be attributed to the weakening of the higher coordination Ni-O bonds by the presence of two axial methanol ligands. The nickel-oxygen distance to the methanol ligands (Ni-O3 = 2.1000(18) Å ) compares well with the values (2.127 Å and 2.066 Å ) given for the similar tetragonal nickel(II) complexes containing two methanol ligands in axial positions and two O-N bidentate ligands in the equatorial plane [10,11]. The bond angles within the coordination sphere are close to the ideal value of 90°for a tetragonal geometry [O1-Ni-O2 = 91.60(7)°, O1-Ni-O3 = 90.43(7)°, O2-Ni-O3 = 91.95(7)°] ( Table 1).…”
