The quest for trifluorophosphine as a bridging ligand in homoleptic binuclear and tetranuclear cobalt complexes Transition metal complexes with bridging PF3 groups are unknown analogous to metal carbonyls with bridging carbonyl groups. The possibility of bridging PF3... Yang, Hua-Qing,Li, Qian-Shu,...
We report the cytotoxicity toward B16 cells and antitumor activity in three transplantable tumor models of a series of ionic, tetrahedral, bischelated gold diphosphine complexes of the type [Au1(R2PYPR2')2]X, where Y = (CH2)2, (CH2)3, or cis-CH = CH. The anion (X = Cl, Br, I...
