“…Hirshfeld analysis is a well-known method for exploring crystal data to gain deeper insight into the characteristics of intermolecular interactions in a solid state [ 52 , 53 , 54 , 55 ]. For each crystal, a cluster of the closest molecules was generated and the unique pair energies have been calculated using CrystalExplorer [ 56 , 57 , 58 ] with the CE-B3LYP model derived from wavefunctions computed by Gaussian09 [ 59 ].…”

Lauric acid was used to synthesize the low-molecular-weight organogelators (LMOGs), derivatives of two endogenous (L)-alanine, (L)-leucine, and three exogenous (L)-valine, (L)-phenylalanine, and (L)-proline amino acids. The nature of processes responsible for the gel formation both in polar and in apolar solvents of such compounds is still under investigation. Knowing that the organization of surfactant molecules affects the properties of nano scale materials and gels, we decided to elucidate this problem using crystallographic diffraction and energy frameworks analysis. The single crystals of the mentioned compounds were produced successfully from heptane/tBuOMe mixture. The compounds form lamellar self-assemblies in crystals. The energetic landscapes of single crystals of a series of studied amphiphilic gelators have been analyzed to explore the gelling properties. The presented results may be used as model systems to understand which supramolecular interactions observed in the solid state and what energy contributions are desired in the designing of new low-molecular-weight organic gelators.

“…These structures proved the flexibility of selected bi-compartmental N2O2-O2O'2 Schiff base skeletons to accommodate simultaneously the Pd(II) or Pt(II) ions (which demand a special planar tetragonal coordination environment) in the inner N2O2 pocket and lanthanide ions in the outer O2O'2 binding site. In case of heterotrinuclear Pd(II)-4f metal complexes the appropriate geometry for the auxiliary lanthanide ion was achieved by a propeller like arrangement of two Schiff base ligands resulting in linear trinuclear complexes that was previously observed for classic nonPGM homonuclear 3d or heteronuclear 3d-4f species enabling via bridges intermetallic interactions [162][163][164][165][166].…”

“…Classic bi-or Trinuclear Systems, which are N 2 O 2 -compartmental Schiff Bases The N 2 O 2 -compartmental Schiff base (Scheme 2e,f) are intensively used for studying of various transition metal complexes, however, there are only two structural reports on a series of crystal structures of classic heterobi-and heterotrinuclear systems in which the platinum group metals (Pt or Pd) were coordinated inside the N 2 O 2 -compartmental Schiff bases coordination site (Figure 10a,b; DEMPUJ and DIPDAK) [44,157]. These structures proved the flexibility of selected bi-compartmental N 2 O 2 -O 2 O' 2 Schiff base skeletons to accommodate simultaneously the Pd(II) or Pt(II) ions (which demand a special planar tetragonal coordination environment) in the inner N 2 O 2 pocket and lanthanide ions in the outer O 2 O' 2 binding site.In case of heterotrinuclear Pd(II)-4f metal complexes the appropriate geometry for the auxiliary lanthanide ion was achieved by a propeller like arrangement of two Schiff base ligands resulting in linear trinuclear complexes that was previously observed for classic nonPGM homonuclear 3d or heteronuclear 3d-4f species enabling via bridges intermetallic interactions[162][163][164][165][166].…”

Chemistry of Schiff base (SB) ligands began in 1864 due to the discovery made by Hugo Schiff (Schiff, H., Justus Liebigs Ann. der Chemie 1864, 131 (1), 118–119). However, there is still a vivid interest in coordination compounds based on imine ligands. The aim of this paper is to review the most recent concepts on construction of homo- and hetero-oligonuclear Schiff base coordination compounds narrowed down to the less frequently considered complexes of platinum group metals (PGM). The combination of SB and PGM in oligonuclear entities has several advantages over mononuclear or polynuclear species. Such complexes usually exhibit better electroluminescent, magnetic and/or catalytic properties than mononuclear ones due to intermetallic interactions and frequently have better solubility than polymers. Various construction strategies of oligodentate imine ligands for coordination of PGM are surveyed including simple imine ligands, non-innocent 1,2-diimines, chelating imine systems with additional N/O/S atoms, classic N2O2-compartmental Schiff bases and their modifications resulting in acyclic fused ligands, macrocycles such as calixsalens, metallohelical structures, nano-sized molecular wheels and hybrid materials incorporating mesoionic species. Co-crystallization and formation of metallophilic interactions to extend the mononuclear entities up to oligonuclear coordination species are also discussed.
