The subtle balance of the metrics of the highly supple 5,5′-pyridyl-3,3′-bis-1H-pyrazolate and the variable coordination numbers of Cu­(I) favor the stabilization of a [4 × 4] grid complex with all Cu­(I). It has numerous cuprophilic bonds (Cu···Cu = 2.56–3.02 Å), and consequently, exhibits strong orange luminescence that fades upon insertion of solvents without loss of crystallinity.
