## Abstract [W(≡CR)Br(CO)~2~(NC~5~H~4~Me‐4)~2~] (R = C~6~H~3~Me~2~‐2,6 1a, C~6~H~2~Me~3~‐2,4,6 1b) react with K[H~2~B(pz)~2~] (pz = pyrazol‐1yl) to provide two interconverting isomers of [W(≡CR)(CO)~2~(NC~5~H~4~Me‐4){H~2~B(pz)~2~}] (2), one isomer having been structurally characterised for R = C~6~
