Chlorido-(η6-p-cymene)-(bis(pyrazol-1-yl)methane-κ2N,N′)Osmium(II) Tetrafluoroborate, C17H22BClF4N4Os

The powder of the arene osmium(II) complex, [Os(II)(dpzm)(η6-p-cym)Cl]BF4 (dpzm = di(1H-pyrazol-1-yl)methane; η6-p-cym para-cymene), with a formula C17H22BClF4N4Os (referred to herein as 1) was isolated from reaction [(η6-p-cym)Os(μ-Cl)(Cl)]2 dpzm dissolved in acetonitrile and under flow nitrogen gas. It characterized by spectroscopic techniques (viz., FTIR, 1H NMR, UV-Visible absorption). Yellow crystal blocks 1 were grown slow evaporation methanolic solution its powder. single-crystal X-ray structure solved diffraction analysis on Bruker APEX Duo CCD area detector diffractometer using Cu(Kα), λ 1.54178 Å radiation source, crystallizes monoclinic system C2/c (no. 15) space group.
