摘要

Two new compounds containing the (acetylido)(cyanido)aurate(I) anion are reported. Their solid-state structures with the monocation PPN, bis(triphenylphosphane)iminium, are reported as a product containing a water molecule and an acetone molecule for the phenylacetylide compound, and as a monohydrate in the case of the t-butylacetylide compound. The gold atom is linearly coordinated with normal Au-C bonds in both cases (1.97-1.99 angstrom). Hydrogen bond chains are found from N to water and from water to acetone, with H bond D center dot center dot center dot A contact distances of 2.92 angstrom (O center dot center dot center dot O) and 3.01 angstrom (O center dot center dot center dot N) for the phenylacetylide compound. The PPN cation has normal bond lengths in both compounds and no short contacts with other atoms in the lattice are observed.
