- Abstract
A new Co(II) complex 2 with ligand 4,4,4-trifluoro-1-(6-methoxynaphthalen-2-yl) butane-1,3-dione 1 and pyridine are prepared and crystallized from an acetone solution. The obtained red and transparent crystal conforms to the empirical formula of Co(CHOF)·(CHN). It crystallizes in monoclinic, space group C2/c with a = 23.3152(14), b = 12.0225(7), c = 15.3950(10) Å, β = 124.1360(10)°, V = 3571.8(4) Å, Z = 4, CHCoFNO, Mr = 807.59, F(000) = 1652, Dc = 1.502 g/cm, μ = 0.564 mm, the final R = 0.0466 and wR = 0.1043 for 3901 observed reflections with I > 2σ(I). X-ray structural analysis revealed that the Co(II) atom is coordinated by two oxygen atoms of 1,3-dione ligands 1 and two nitrogen atoms of pyridines, forming a distorted octahedron coordination geometry. Graphical Abstract: A new cobalt complex 2 bis(pyridine)bis(4,4,4-trifluoro-1-(6-methoxynaphthalen-2-yl)butane-1,3-dione) Cobalt(II), Co(CHOF)·(CHN), has been synthesized and characterized by X-ray structure determination. In the complex, the Co(II) atom is coordinated by four oxygen atoms of the β-diketonate ligands and two nitrogen atoms of pyridines, forming a distorted octahedron coordination geometry.[Figure not available: see fulltext.]
