In this study, a new equimolar (1:1:1) mixed ligand Cu(II) polymer, [Cu(IDA)(ImP)]n (1) with iminodiacetato (IDA) and imidazo[1,2-a]-pyridine (ImP) was synthesized and characterized by single crystal X-ray diffraction analysis. X-ray crystallography reveals that compound (1) consists of polymeric zigzag chain along [010] the carboxylate carbonyl oxygen atom by two-fold symmetry screw axis. The solid-state structure is stabilized through C–H···O hydrogen bonds and C–H···π interactions that lead the molecules to generate two-dimensional supramolecular assemblies. The intricate combinations of hydrogen bonds and C–H···π interactions are fully described along with computational studies. A thorough analysis of Hirshfeld surface and fingerprint plots elegantly quantify the interactions involved within the structure. The binding energies associated with the noncovalent interactions observed in the crystal structure and the interplay between them were calculated using theoretical DFT calculations. Weak noncovalent interactions were analyzed and characterized using Bader’s theory of ‘‘atoms-in-molecules’’ (AIM). Finally, the solid-state supramolecular assembly was characterized by the “Noncovalent Interaction” (NCI) plot index.

In the title compound, C17H15NO4(alternative name;O-benzyl-L-tyrosineN-carboxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benzyloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°, and are inclined to the oxazolidine ring by 59.16 (11) and 58.42 (11)°, respectively. In the crystal, molecules are linked by N—H...O and C—H...O hydrogen bonds, forming ribbons propagating along [010]. The ribbons are linked by C—H...π interactions, forming a three-dimensional supramolecular structure. The oxazolidine rings of adjacent ribbons are arranged into a layer parallel to theabplane. This arrangement is favourable for the polymerization of the compound in the solid state.

Two novel mixed 1D–2D coordination polymers based on 2D [Ln(4,4′-bpdo)2(NO3)2(H2O)2]+n sheets and 1D [Ln2(4,4′-bpdo)2(C4AS)(NO3)(H2O)9]n chains (Ln = Sm for 1 and Ln = Nd for 2) sustained by π⋯π interactions and lattice water facilitated hydrogen bonds have been established.

A novel bridging asymmetric benzimidazole ligand, 4-{2-[3-(pyridin-4-yl)phenyl]-1H-benzimidazol-1-ylmethyl}benzoic acid, was used to construct three isomorphous two-dimensional coordination polymers, namelycatena-poly[chlorido(μ3-4-{2-[3-(pyridin-4-yl)phenyl]-1H-benzimidazol-1-ylmethyl}benzoato)zinc(II)], [Zn(C26H18N3O2)Cl]n, (I), and the bromide, (II), and iodide, (III), analogues. Neighbouring two-dimensional networks are stacked into three-dimensional frameworksviainterlayer π–π interactions. The luminescent properties of (I)–(III) were investigated and they display an obvious red-shift in the solid state at room temperature.

The title compound, C8H4INO2, has a single planar molecule in the asymmetric unit, with the non-H atoms possessing a mean deviation from planarity of 0.058 Å. The molecules dimerize in the solid state through N—H...O hydrogen bonds. There are intermolecular I...O close contacts of 3.193 (4) Å that link the molecules into infinite chains along [20-1]. No π–π interactions were observed in the structure.

We report novel pseudorotaxanes based on the complexation between pillar[4]arene[1]quinone and 1,10-dibromodecane. The complexation is found to have a 1:1 host–guest complexation stoichiometry in chloroform but a 2:1 host–guest complexation stoichiometry in the solid state. From single crystal X-ray diffraction, the linear guest molecules thread into cyclic pillar[4]arene[1]quinone host molecules in the solid state, stabilized by CH∙∙∙π interactions and hydrogen bonds. The bromine atoms at the periphery of the guest molecule provide convenience for the further capping of the pseudorotaxanes to construct rotaxanes.
