Abstract
[L2Cu4I4]n (1) based on a cubic [Cu4I4] node and ditopic, bridging bis(triazole) (L = 2,6-bis((1H-1,2,3-triazol-1-yl)methyl)pyridine) is a unique and highly symmetric cubane cluster based coordination polymer with strong yellow emission. Comparison with similar coordination polymers permits a structure activity relationship and reveals that the emission energy for these [Cu4I4] cluster-based materials occurs in the mid-range of Cu⋅⋅⋅Cu distances and tetrahedral geometry index values.
