The combination of pentafluorobenzoate (Pfb), benzoate (Bz) anions, with 1,10-phenanthroline (Phen) within a single compound leads to the formation of crystals of previously reported homoanionic complexes. When using 2,3,5,6-tetrafluoro-4-(trifluoromethyl)phenylacetate (Tfpha) or 3,5-dinitrobenzoate (Dnb) anions instead of pentafluorobenzoate, it was possible to isolate mixed-anion compounds [Cd<sub>2</sub>(Phen)<sub>2</sub>(Tfpha)<sub>2</sub>(Bz)<sub>2</sub>] (I), [Cd<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>3</sub>(Bz)<sub>3</sub>][Cd<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>4.5</sub>(Bz)<sub>1.5</sub>] (II), [Zn<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>4</sub>(Bz)<sub>2</sub>] · 2(C<sub>6</sub>H<sub>6</sub>) (III), [ZnCd<sub>2</sub>(Phen)<sub>2</sub>(Dnb)<sub>5</sub>(Bz)] · 3 (C<sub>6</sub>H<sub>6</sub>) · (MeOH) (IV). In the structure of compounds II and IV, according to X-ray diffraction data, in some anion sites the Bz-and Dnb-anions are refined simultaneously with different occupancies. Using the compounds [Cd<sub>2</sub>(Phen)<sub>2</sub>-(Dnb)<sub>2</sub>(Pha)<sub>2</sub>] (V) and [Zn(H<sub>2</sub>O)(Phen)(Dnb)(Pha)]·MeCN (VI, Pha – phenylacetate anion) as examples, it is shown that mixed-anion complexes can also be formed when a conformationally flexible phenylacetate anion is combined with a stereochemically more rigid 3,5-dinitrobenzoate anion at zinc and cadmium centers. The synthesized compounds were characterized by X-ray diffraction analysis (CCDC nos. 2443227, 2443228, 2443229, 2443230, 2443231, and 2443232, respectively), IR spectroscopy, and CHN analysis. It has been found that the main contribution to the stabilization of the crystal packings is provided by π···π, C–H···F, N–O···π, and NO<sub>2</sub>···NO<sub>2</sub>.</p></abstract><trans-abstract xml:lang="ru"><p>Исследована возможность получения смешаноанионных комплексов кадмия и цинка с различными сочетаниями анионов монокарбоновых кислот. При совмещении в составе соединений пентафторбензоатного (Pfb), бензоатного (Bz) анионов и 1,10-фенантролина (Phen) формируются кристаллы ранее описанных гомоанионных соединений. При использовании 2,3,5,6-тетрафтор-4-(трифторметил)фенилацетатного (Tfpha) или 3,5-динитробензоатного (Dnb) анионов вместо пентафторбензоатного удалось выделить смешаноанионные соединения [Cd<sub>2</sub>(Phen)<sub>2</sub>(Tfpha)<sub>2</sub>(Bz)<sub>2</sub>] (I), [Cd<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>3</sub>(Bz)<sub>3</sub>][Cd<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>4.5</sub>(Bz)<sub>1.5</sub>] (II), [Zn<sub>3</sub>(Phen)<sub>2</sub>(Dnb)<sub>4</sub>(Bz)<sub>2</sub>] · 2(C<sub>6</sub>H<sub>6</sub>) (III), [ZnCd<sub>2</sub>(Phen)<sub>2</sub>(Dnb)<sub>5</sub>(Bz)] · 3 (C<sub>6</sub>H<sub>6</sub>) · (MeOH) (IV). В структуре соединений II и IV по данным PCA в некоторых позициях анионов уточняются одновременно Bz- и Dnb-анионы в различном соотношении. На примере соединений [Cd<sub>2</sub>(Phen)<sub>2</sub>(Dnb)<sub>2</sub>(Pha)<sub>2</sub>] (V) и [Zn(H<sub>2</sub>O)(Phen)(Dnb)(Pha)] · MeCN (VI, Pha = фенилацетатный анион) показано, что смешаноанионные комплексы также формируются при совмещении на ионах цинка и кадмия конформационно подвижного фенилацетатного и стереохимически более жесткого 3,5-динитробензоатного. Синтезированные соединения I–VI охарактеризованы методом PCA (CCDC № 2443227, 2443228, 2443229, 2443230, 2443231, 2443232 соответственно), ИК-спектроскопии и CHN-анализа. Детально проанализирована структура и кристаллические упаковки полученных комплексов. Выявлено, что основной вклад в стабилизацию кристаллических упаковок вносят NO<sub>2</sub> взаимодействия π···π, C–H···F, N–O···π, NO<sub>2</sub>···NO<sub>2</sub>.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mixed-anion complexes</kwd><kwd>zinc</kwd><kwd>cadmium</kwd><kwd>X-ray structural analysis</kwd><kwd>non-covalent interactions</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>смешаноанионные комплексы</kwd><kwd>цинк</kwd><kwd>кадмий</kwd><kwd>рентгеноструктурный анализ</kwd><kwd>нековалентные взаимодействия</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the grant of the Russian Science Foundation (No. 22-73-10192).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта Российского научного фонда (№ 22-73-10192).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Xu Y., Wang C., Jiang T. et al. //J.
