(a) One of the six β-quartz-like nets of Zn[Au(CN)2]2 viewed down its crystallographic c-axis; this framework consists of ZnN4 tetrahedra connected via flexible dicyanoaurate (N–C–Au–C–N) molecular linkers. (b) An alternate view that highlights the honeycomb-like nature of its hexagonal pores and also the cross-bracing effect of helical aurophilic chains running perpendicular to the c crystal axis.
