摘要：

The H-1 NMR analysis of the paramagnetic trans-dihalogeno-ruthenium(IV) and osmium(IV) porphyrins reveals that the halides have a pronounced effect on both the magnitude and the direction of charge transfer between the metal and the porphyrin, that the degree of covalency of metal-halide bonds increases in the order of Mn-III < Ru-IV < Os-IV, and that the relative strength of halogen-to-metal pi-donation is Cl < Br < I.
