T-shaped intermolecular CH ⋯π(CC) interactions in chloroform solvates of gold(I) ethyne complexes

The molecular structures of the chloroform solvates of the ethynediyl digold complexes NpPh2P–Au–CC–Au–PNpPh2·2CHCl31(Np = naphthyl) and Np2PhP–Au–CC–Au–PNp2Ph·6CHCl32 have been determined by X-ray techniques; although none of the compounds have short Au ⋯ Au contacts compounds 1 and 2 do exhibit novel C–H ⋯π interactions between the protons of CHCl3 molecules and the π-electron system of the CC bond.
