    Chlorido-(η 6 -p-cymene)-(bis(pyrazol-1-yl)methaneκ 2N,N0 )Osmium(II) Tetrafluoroborate, C17H22BClF4N4Os
    (MDPI, 2022) Mambanda, Allen; Kanyora, Amos K.; Ongoma, Peter; Gichumbi, Joel; Omondi, Reinner O.
    The powder of the arene osmium(II) complex, [Os(II)(dpzm)(η 6 -p-cym)Cl]BF4 (dpzm = di(1H-pyrazol-1-yl)methane; η 6 -p-cym = para-cymene), with a formula of C17H22BClF4N4Os (referred to herein as 1) was isolated from the reaction of [(η 6 -p-cym)Os(µ-Cl)(Cl)]2 with dpzm dissolved in acetonitrile and under a flow of nitrogen gas. It was characterized by spectroscopic techniques (viz., FTIR, 1H NMR, UV-Visible absorption). Yellow crystal blocks of 1 were grown by the slow evaporation from the methanolic solution of its powder. The single-crystal X-ray structure of 1 was solved by diffraction analysis on a Bruker APEX Duo CCD area detector diffractometer using the Cu(Kα), λ = 1.54178 Å as the radiation source, and 1 crystallizes in the monoclinic crystal system and the C2/c (no. 15) space group.
