N2 - A series of square planar trans bis-N-heterocyclic carbene palladium(II) bis(acetylide) complexes of the type [( iPr 2-bimy) 2Pd(C≡C-R) 2] (bimy = benzimidazolin-2-ylidene) (R = C 6H 5, C 6H 4F, C 6H 4OMe, SiMe 3, C 4H 3S, C 5H 4N, C 6H 4C≡CC 6H 5 and 1-pyrene) were prepared by the addition of the corresponding lithium acetylides to the starting ( iPr 2-bimy) 2PdBr 2 complex in good to modest yields. The molecular structures of ( iPr 2-bimy) 2Pd(C≡C-C 6H 5) 2 (1) and [( iPr 2-bimy) 2Pd(C≡C-SiMe 3) 2] (4) were determined by single-crystal X-ray diffraction studies. UV/vis absorption studies reveal significant spectral changes depending on the nature of the acetylide ligands bound to the palladium center.
