A Rare Structural Motif for a Luminescent Cu(I) Coordination Polymer with 3-(Pyridin-2-yl)triimidazotriazine / D. Malpicci, D. Blasi, D. Marinotto, A. Forni, E. Cariati, E. Lucenti, L. Carlucci. - In: CRYSTALS. - ISSN 2073-4352. - 13:1(2023), pp. 149.1-149.10. [10.3390/cryst13010149]
Abstract:
The coordination ability of the pyridine derivative of cyclic triimidazole, namely 3-(pyridin 2-yl)triimidazotriazine (TT-Py) towards Cu(I) was explored. TT-Py is an appealing nitrogen-rich
ligand characterized by the presence of three imidazole nitrogen atoms with trigonal symmetry and a
pyridine moiety, available for coordination to metal ions. The multidentate nature of TT-Py allows
to isolate, by reaction with CuI at room temperature, the one-dimensional coordination network
[Cu2I2(TT-Py)]n (1). 1 is characterized by a rare structural network built-up by the combination in
a 1:2 ratio of two common motifs for Cu(I) halides coordination polymers, which are the double stranded stair and the zig-zag chain. 1 displays one broad long-lived emission in the solid state, which
has been associated, by the support of DFT and TDDFT calculation, with low-energy transitions of
MLCT or XMLCT character.
