Abstract

The majority of six-coordinate d⁴ osmium/ruthenium(IV) porphyrin complexes [M(por)X₂] have been found to be paramagnetic and have linear X-M-X structural units. However, an exception is found for [Os(por)R₂] and [Os(por)(SR)₂] (R = alkyl), which are diamagnetic. While the S-Os-S unit in [Os(por)(SR)₂] is linear, the R-Os-R unit in [Os(por)R₂] is found to be significantly bent. In this note, the geometric features and electronic structures of the dialkyl and dithiolate complexes of osmium(IV) porphyrins have been investigated by density functional calculations.
