The influence of arene/perfluoroarene ratio on the structure and crystal packing of carboxylate and nitrate-carboxylate complexes of Cd, Cd-Tb and Cu was studied, using the following compounds: pentafluorobenzoate (pfb) and 4-allyl-2,3,5,6-tetrabenzoate (Afb) anions and 1,10-phenanthroline (phen) composition [Cd(pfb)2(phen)]n (1), [Cd(NO3)(pfb)(phen)]n (2), [Tb2Cd2(pfb)10(phen)2]. 3MeCN]n (3), [Tb2Cd2(NO3)2(pfb)8(phen)2.1.5MeCN]n (4), [Cu2(Afb)4(phen)2] (5), [Cu2(NO3)2(Afb)2(phen)2] (6). It is shown that the main contribution to the stabilization of the crystal packing of coordination polymers 1–4 and molecular binuclear complexes 5 and 6 can be attributed to non-covalent π···π, C-H···F, and C-F···π interactions. It was found that the partial exchange of pfb or Afb anions on compact NO3− anions leads to a decrease in steric hindrance, a more efficient overlap of aromatic fragments, and a significant change in the geometry of complexes. Synthesized compounds were characterized by X-ray diffraction analysis, IR spectroscopy, and CHN analysis. The thermal stability of complexes 1 and 2 was studied. Non-covalent interactions were analyzed using the Hirshfeld surface method.

Heterometallic d‐4f coordination complexes are of paramount interest in modern coordination chemistry because of their potential applications in organic light‐emitting devices and spintronic materials. Here we report the synthesis and thorough investigation of Ln and MLn (M = Zn, Cd; Ln = Sm, Eu, Gd, Tb) molecular complexes based on 2‐furancarboxylic acid anion (Hfur): [Ln2(NO3)2(fur)4(DME)2] (Ln = Eu, Gd, Tb; DME is dimethoxyethane) and [M2Ln2(NO3)2(fur)8(bpy)2] (M = Zn, Cd; Ln = Eu, Gd, Tb, Sm; bpy is 2,2′‐bipyridyl). The structure and isostructural nature of compounds were determined based on the single‐crystal and powder X‐ray diffraction data. The photophysical properties of the obtained compounds were studied in detail: The energies of the triplet levels of the furoate anion and d‐blocks {M(fur)2(bpy)} (M = Zn, Cd), the relaxation times of the excited states, and the quantum yields were determined. Critical step from Ln complexes to ZnLn and CdLn (Ln = Eu, Tb) is accompanied by an increase in quantum yields, which correlates with a change in the energy of the triplet level of the aromatic part of the complexes and with the results of quantum chemical calculations indicating different schemes for the origination of triplet levels in MLn compounds.
