A series of platinum(II) boryl complexes of general formula trans ‐[(Cy 3 P) 2 Pt(Br)(BX 2 )], including the rare dibromoboryl species trans ‐[(Cy 3 P) 2 Pt(Br)(BBr 2 )], were synthesized by oxidative addition of the BBr bond of a number of bromoboranes to [Pt(PCy 3 ) 2 ]. X‐ray diffraction studies were performed on several such compounds. Comparison of the PtBr bond lengths allowed an empirical assessment of the trans ‐influence of different boryl ligands. A trans ‐influence scale was thus deduced and the results were compared with those previously computed for compounds of the type trans ‐[(Me 3 P) 2 Pt(Cl)(BX 2 )].
