“…The six oxygen and the three nitrogen atoms form a distorted tricapped trigonal prism with the capped positions occupied by the nitrogen atoms (see Figure 2). The same arrangement has been found in the Ln III series [77,78,79,80,81,82,83,84,85,86,87,88,89,90,91], An III series [5,6,92] and Ce IV [85,93] as well as in U IV crystals [9].…”

“…In particular, molecular recognition and selective binding of H 3 PG and other associated resorcinol and naphtalenediol-type co-formers involved various polynuclear d-metal ions clusters serving as the molecular hosts [31,34,[39][40][41][42][43][44][45][46]. However, anionic d-metallates or f-metallates were moderately represented in these studies, count-ing some examples of pyridine-dicarboxylate complexes forming the hydrogen-bonded networks with pyridinium and polypyridinium cations [34,43,45,46].…”

Supramolecular cis-“Bis(Chelation)” of [M(CN)6]3− (M = CrIII, FeIII, CoIII) by Phloroglucinol (H3PG)

Studies on molecular co-crystal type materials are important in the design and preparation of easy-to-absorb drugs, non-centrosymmetric, and chiral crystals for optical performance, liquid crystals, or plastic phases. From a fundamental point of view, such studies also provide useful information on various supramolecular synthons and molecular ordering, including metric parameters, molecular matching, energetical hierarchy, and combinatorial potential, appealing to the rational design of functional materials through structure–properties–application schemes. Co-crystal salts involving anionic d-metallate coordination complexes are moderately explored (compared to the generality of co-crystals), and in this context, we present a new series of isomorphous co-crystalline salts (PPh4)3[M(CN)6](H3PG)2·2MeCN (M = Cr, 1; Fe, 2; Co 3; H3PG = phloroglucinol, 1,3,5-trihydroxobenzene). In this study, 1–3 were characterized experimentally using SC XRD, Hirshfeld analysis, ESI-MS spectrometry, vibrational IR and Raman, 57Fe Mössbauer, electronic absorption UV-Vis-NIR, and photoluminescence spectroscopies, and theoretically with density functional theory calculations. The two-dimensional square grid-like hydrogen-bond {[M(CN)6]3–;(H3PG)2}¥ network features original {[M(CN)6]3–;(H3PG)4} supramolecular cis-bis(chelate) motifs involving: (i) two double cyclic hydrogen bond synthons M(-CN×××HO-)2Ar, {[M(CN)6]3–;H2PGH}, between cis-oriented cyanido ligands of [M(CN)6]3– and resorcinol-like face of H3PG, and (ii) two single hydrogen bonds M-CN×××HO-Ar, {[M(CN)6]3–;HPGH2}, involving the remaining two cyanide ligands. The occurrence of the above tectonic motif is discussed with regard to the relevant data existing in the CCDC database, including the multisite H-bond binding of [M(CN)6]3– by organic species, mononuclear coordination complexes, and polynuclear complexes. The physicochemical and computational characterization discloses notable spectral modifications under the regime of an extended hydrogen bond network.

“…In the third step, the modified hostguest complex formed in the second step takes up another guest molecule. From isothermal calorimetry, the binding 123 Analysis of structures have shown that the interactions between the anions interacting with cations to hold 2,3-or 2,7-naphthalenediols in 44 and 45 have close similarity. In such host templates, two lanthanum tris-pdc anions are bridged by hydrogen bonding with one 4,4 -bipyridinium cation.…”

Various non-covalently linked inorganic self-assemblies formed by the supramolecular interacting sites located at the ligands are discussed. The impetus for this rapidly growing topic on the construction of robust assemblies is elucidated by select examples that are associated with interesting structures and properties. The review includes discussion on the stabilization of different assemblies of nucleobases in the non-covalent assemblies of inorganic complexes. The participation of the guest molecules in the formation of self-assemblies with hosts to make extra space or voids for intake of the guest, water-assisted assemblies, changes in the structures guided by cations, and aggregation-induced photoluminescence in the self-assemblies of metal complexes are presented. Fine-tuning of non-covalent self-assemblies of metal complexes by changing ligands or by other components, which modify the guest recognition abilities is elucidated. The discussions are based on selected examples of self-assemblies that use supramolecular features of peripheral part of ligands or ligand of a complex that helps one to identify templates for weak interactions and for molecular recognition.
