摘要: Abstract Two new compounds containing the (acetylido)(cyanido)aurate(I) anion are reported. Their solid-state structures with monocation PPN, bis(triphenylphosphane)iminium, reported as a product water molecule and an acetone for phenylacetylide compound, monohydrate in case of t -butylacetylide compound. The gold atom is linearly coordinated normal Au–C bonds both cases (1.97–1.99 A). Hydrogen bond chains found from N to acetone, H D⋯A contact distances 2.92 A (O⋯O) 3.01 A (O⋯N) PPN cation has lengths no short contacts other atoms lattice observed. luminescence properties have been measured solid powders. compound shows medium strength emission two peaks at 431 454 nm when excited 310 nm. excitation spectra monitored 454 nm, respectively, show similar broad band maximum 310–317 nm. Surprisingly, displays negligible luminescence.
