Polymorphic Copper Iodide Anions: Luminescence Thermochromism and Mechanochromism of (PPh4)2[Cu2I4]

“…33 Another binuclear anion is [Cu2I4] 2which has been encountered in several associations with different organic and inorganic cations. 34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66 The photophysical properties of these compounds have been rarely characterized, [Cu2I4] 2being simply treated as an inorganic counter-anion and not as an emissive species by itself. In particular, with the tetraphenylphosphonium cation, the polymorphic structure of (PPh4)2[Cu2I4] has been reported but no photophysical characterization has been investigated.…”

Two Nanometer-Sized High-Nuclearity Homometallic Bromide Clusters (M26Br38)12– (M = Cu, Ag): Syntheses, Crystal Structures, and Efficient Adsorption Properties

“…To date, numerous d 10 M­(I) halides [M x Y y ] ( y − x )– (X = Cl, Br, I; M = Cu, Ag) have been identified by single-crystal X-ray diffraction. They may be discrete or polymeric . The incidence and rationalization of the detailed geometry of the particular halogenometal­(I) anion motif and their degree of condensation are apparently influenced by the size, shape, and charge distribution of the cations involved .…”

“…The incidence and rationalization of the detailed geometry of the particular halogenometal­(I) anion motif and their degree of condensation are apparently influenced by the size, shape, and charge distribution of the cations involved . There are only two example availables of compounds with high symmetry (space group I 4̅3 m ), and they are mononuclear. , There are some isolated (nonpolymeric) high-nuclearity copper cages, including 1 Cu 3 , 18 Cu 4 , − 5 Cu 5 , , and 3 Cu 8 − clusters. However, there are very few discrete high-nuclearity silver cages, including 3 Ag 4 − and 3 Ag 6 − clusters.…”

Therefore, compounds 1 and 2 represent the first high-symmetry and high-nuclearity homometallic Cu 26 (Ag 26 ) clusteric cages.…”
