The paramagnetic complexes (TmtBu)CoX (X = Cl, Br, I) have been readily prepared and structurally characterized and provide a convenient entry into cobalt(II) tris(mercaptoimidazolyl)borate chemistry. A number of derivatives, including mononuclear triphenylphosphine adducts [(TmtBu)Co(PPh3)]X and dinuclear compounds [Co2(TmtBu)2X]Y, have been prepared in order to ascertain whether cobalt is a reliable surrogate for zinc in biological systems, particularly in sulfur-rich coordination environments. The structure of the first cobaltaboratrane is also reported.
顺磁性配合物(TmtBu)CoX(X = Cl, Br, I)已被轻松制备并结构表征,为钻(II)三(巯基咪唑基)硼酸盐化学提供了便利的切入点。为了确保钻是否是生物系统中可靠的锌替代品,尤其是在富含硫的配位环境中,制备了许多衍生物,包括单核的、含三苯基膦的加合物[(TmtBu)Co(PPh3)]X和双核化合物[Co2(TmtBu)2X]Y。同时,本文还报道了首个钴硼杂苯的结构。
