All title complexes were crystallographically characterized to reveal a zig\u2010zag chain arrangement for 1<\/jats:bold> and 3<\/jats:bold>\u20135<\/jats:bold>, whereas 6<\/jats:bold>\u201310<\/jats:bold> possess metallocyclic frameworks with different degree of metal\u2010metal bonding. The d10<\/jats:sup>\u2013d10<\/jats:sup> interactions were evaluated by the quantum theory of atoms in molecules (QTAIM) computational approach. The photophysical properties of 1<\/jats:bold>\u201310<\/jats:bold> were investigated in the solid state and supported by theoretical analysis. The emission of compounds 1<\/jats:bold> and 3<\/jats:bold>\u20135<\/jats:bold>, dominated by metal\u2010to\u2010ligand charge transfer (MLCT) transitions located within {CuP<\/jats:bold><\/jats:italic>2<\/jats:bold><\/jats:sup>} motifs, is compatible with thermally activated delayed fluorescence (TADF) behaviour and a small energy gap between the T1<\/jats:sub><\/jats:italic> and S1<\/jats:sub><\/jats:italic> excited states. The luminescence characteristics of 6<\/jats:bold>\u201310<\/jats:bold> are strongly dependent on the composition of the metal core; the emission band maxima vary in the range 484\u2013650\u2005nm with quantum efficiency reaching 0.56 (6<\/jats:bold>). The origin of the emission for 6<\/jats:bold>\u20138<\/jats:bold> and 10<\/jats:bold> at room temperature is assigned to delayed fluorescence. AuCu cluster 9<\/jats:bold>, however, exhibits only phosphorescence that corresponds to theoretically predicted large value \u0394E<\/jats:italic>(S1<\/jats:sub><\/jats:italic>\u2212T1<\/jats:sub><\/jats:italic>). DFT simulation highlights a crucial impact of metallophilic bonding on the nature and energy of the observed emission, the effect being greatly enhanced in the excited state.<\/jats:p>","DOI":"10.1002\/chem.201704642","type":"journal-article","created":{"date-parts":[[2017,11,8]],"date-time":"2017-11-08T03:56:34Z","timestamp":1510113394000},"page":"1404-1415","source":"Crossref","is-referenced-by-count":45,"title":["Cyanide\u2010Assembled
