“…There is a correlation between the metal-carbon distances and the distances between centers of the chelate and phenyl rings, indicating that the chelate and phenyl rings tend to overlap. In the crystal structures there are mutual slipped-parallel orientations of the phenyl and chelate rings [27], indicating that chelate rings can behave similar to organic aromatic rings.…”

“…Recently, a few studies of noncovalent interactions with the π-system of chelate rings were published [18,[23][24][25][26][27][28][29][30][31]. The delocalized π-system of the chelate rings can be considered as a soft base, similar to double and triple bonds or aromatic rings, and could be connected with an assumption that planar chelate rings with delocalized π-bonds can have aromatic character [31].…”

The chelate ring can be involved in CH/π interactions with organic moieties and in stacking interactions with phenyl rings [18,[23][24][25][26][27][28][29][30].…”

“…These interactions were first recognized in square planar complexes of Cu [26]. Recently, the analysis of geometrical parameters in crystal structures of square planar complexes of all transition metals, from the Cambridge Structural Database, shows that there are stacking interactions between phenyl rings and chelate rings with delocalized π-bonds [27]. Short distances between the metal and carbon atom of the phenyl ring, and parallel orientations of the phenyl ring with respect to the coordination plane were found in crystal structures of complexes with chelate rings.…”

Abstract:In order to find out whether metal type influences the stacking interactions of phenyl rings in square-planar complexes, geometrical parameters for Cu, Ni, Pd and Pt complexes, with and without chelate rings, were analyzed and compared. By searching the Cambridge Structural Database, 220 structures with Cu complexes, 211 with Ni complexes, 285 with Pd complexes, and 220 with Pt complexes were found. The results show that the chelate ring has a tendency to make the stacking interaction with the phenyl ring independent of metal type in the chelate ring. However, there are some differences among metals for complexes without a chelate ring. There are a number of structures containing Pd and Pt complexes, without chelate rings, that have short carbon-metal distances and parallel orientations of the phenyl ring with respect to the coordination plane. It was found that some of these complexes have a common fragment, CN, as a part of the ligands. This indicates that the CN supports stacking interactions of square planar complexes with the phenyl ring.

Crystal engineering is an emerging discipline whereby practitioners aim to arrange molecules, both organic and metalorganic, in the crystalline phase by rational design. This challenge requires the exploitation of well‐known supramolecular glues such as hydrogen bonding and coordinate bonding. These are augmented by a myriad of nominally weaker and less directional noncovalent interactions that, increasingly, are being demonstrated as important in crystal structure design. Applications in fields as diverse as pharmaceuticals, photoluminescent materials, and metalorganic frameworks for gas storage are some of the motivations for crystal engineering that draw together scientists from a wide range of disciplines. This illustrated overview summarizes factors that dictate the ways molecules aggregate in the solid state, including a description of the diverse types of noncovalent interactions and other crystal packing principles that have being identified as being important in stabilizing crystal structure. Applications of crystal engineering drawn from both the organic and metalorganic realms are discussed. These include cocrystal formation, solid‐state reactions, and metalorganic framework structures. Furthermore, the importance of in silico studies and data mining as they relate to crystal engineering is highlighted throughout.
