(a) Main building block of the crystal structure of pyrEt at 300 K: a rod of four Au atoms, disordered over two positions along its long axis. Atoms Au4 and Au4′ with their phosphine ligands represent the two alternative disorder variants, as the rod can begin at either `side' along the [010] crystallographic direction. The parts with 50% occupancy are represented as semi-transparent. The atomic displacement parameters are presented exclusively for atoms from the asymmetric unit at 50% probability. Hydrogen atoms have been omitted for clarity. (b) Two distinct conformations of the –PEt3 group present in this structure, viewed along (top) and perpendicular to (bottom) the Au—P bond.
