摘要：

The supramolecular architecture of trinuclear gold(l) pyrazolato aggregates is held together by intermolecular aurophilic attractions, sterically governed by the substituents on the pyrazole rings. A two-dimensional network of [Au(mu-pz)](3) complexes, 1 (pz = pyrazolato anion, C3H3N2-), and a large intricate aggregate of 16 [Au(mu-4-Me-pz)](3) complexes in 2 have been determined crystallographically. Under UV irradiation at ambient temperature, solid samples of 1 and 2 luminesce with lambda(max) = 626 and 631 cm(-1), respectively, attributed to intermolecular Au...Au aurophilic contacts.
