Reaction of trans-[Pt(NC5H4CHBun2)2Cl2] 1 with an excess of HCCR (R = Ph, C6H4Me, C6H4NO2) affords the monomeric complex trans-[Pt(NC5H4CHBun2)2(C
CR)2] (R = Ph 2a, C6H4Me 2b, C6H4NO2 2c), the trans arrangement of the alkynyl ligands being confirmed from spectroscopic data and by an X-ray analysis of 2c; when 1 is treated with 1 equiv. of HC
CC6H2(Me)2C
CH the polymer [Pt(NC5H4CHBun2)2C
CC6H2Me2C
C]n is formed, which is soluble in a range of organic solvents.
