Abstract

A novel octanuclear Ag^I₆–Zn^II₂ heterometallic aggregate, (NH₄)₂{[Zn₂(phen)₂(H₂O)₄][Ag₆(mna)₆]}·2H₂O·2CH₃CH₂OH (1, H₂mna = 2-mercaptonicotinic acid, phen = 1,10-phenanthroline), was stepwisely obtained based on a hexanuclear silver(I) metalloligand using a liquid–liquid diffusion method. It is an exceedingly rare example that exhibits interesting temperature dependent photoluminescence behaviors, including gradual changes in energy and intensity upon cooling.
