Popis:	Details of the formation of the complexes trans-[Co(DH)2(PR3)2]+ (PR3+=PPh3, PMePh2, PMe2, Ph, PBu3) from the reactions of the free phosphines with trans-[Co(DH)2(H2 O)2] are studied polarographically. The ease of formation and the ease of reduction of the bisphosphine complexes correlate better with the cone angles of the phosphines than with their expected relative donor properties. The complexes behave as weak acids (pKa 9.9–10.6) in 95% ethanol, there being no apparent correlation with the nature of the axial ligands.
