The title compound, bis(N,N-diallyl-5-methoxytryptammonium) (5-MeO-DALT) fumarate (systematic name: bis{N-[2-(5-methoxy-1H-indol-3-yl)ethyl]- N-(prop-2-en-1-yl)prop-2-en-1-aminium} (E)-but-2-enedioate), 2C17H23N2O+·C4H2O4 2−, has a single tryptammonium cation and half of a fumarate dianion in the asymmetric unit. The tryptammonium and fumarate ions are held together in one-dimensional chains by a series of N—H...O hydrogen bonds. These chains are combinations of R 4 4(22) rings, and C 2 2(14) and C 4 4(28) parallel chains along [111].

The title compound, (systematic name:N,N′-dibenzyl-3,3′-dimethoxy-1,1′-biphenyl-4,4′-diamine), C28H28N2O2, was synthesized by the reduction of a Schiff base preparedviaa condensation reaction betweeno-dianisidine and benzaldehyde under acidic conditions. The molecule lies on a crystallographic inversion centre so that the asymmetric unit contains one half-molecule. The biphenyl moiety compound is essentially planar. Two intramolecular N—H...O hydrogen bonds occur. The dihedral angle between the terminal phenyl and phenylene rings of a benzidine unit is 48.68 (6)°. The methylene C atom of the benzyl group is disordered over two sets of sites, with occupancy ratio 0.779 (18):0.221 (18). In the crystal, molecules are connected by hydrogen bonding betweeno-dianisidine O atoms and H atoms of the terminal benzyl groups, forming a one-dimensional ladder-like structure. In the data from DFT calculations, the central biphenyl showed a twisted conformation.

The asymmetric unit consists of a {Ba[Co(H–2L1)](ClO4)(H2O)}+cationic fragment and a non-coordinating ClO4−anion. In the neutral [Co(H–2L1)] moiety, the cobalt ion is hexacoordinated in a trigonal–prismatic fashion by the surrounding N4O2donor set. The Ba2+ion is nine-coordinated and exhibits a distorted [BaO9] monocapped square-antiprismatic geometry, the six oxygen atoms coming from three distinct [Co(H–2L1)] moieties, while the remaining three vertices are occupied by the oxygen atoms of a bidentate perchlorate anion and a water molecule. A barium–μ2-oxygen motif develops along theaaxis, connecting symmetry-related dinuclear BaII–CoIIcationic fragments in a wave-like chain, forming a one-dimensional metal coordination polymer. Non-coordinating ClO4−anions are located in the space between the chains. Weak C—H...O hydrogen bonds involving both coordinating and non-coordinating perchlorate anions build the whole crystal architecture. To our knowledge, this is the first example of a macrocyclic ligand forming a BaII-based one-dimensional coordination polymer, containing CoIIions surrounded by a N4O2donor set.

In the title compound, [Mg(C44H28N4)(H2O)2]·C12H24O6, the MgIIcation lies on an inversion center and is octahedrally coordinated by the four N atoms of the deprotonated tetraphenylporphyrin (TPP) ligand and by two water molecules. The asymmetric unit contains one half of the [Mg(TPP)(H2O)2] complex and one half of an 18-crown-6 molecule. The average equatorial magnesium–pyrrole N atom distance (Mg—Np) is 2.071 (1) Å and the axial Mg—O(H2O) bond length is 2.213 (1) Å. The crystal packing is stabilized by two O—H...O hydrogen bonds between coordinating water molecules and adjacent 18-crown-6 molecules, and exhibits a one-dimensional supramolecular structure along theaaxis. The supramolecular architecture is futher stabilized by weak C—H...π interactions. The 18-crown-6 molecule is disordered over two sets of sites with an occupancy ratio of 0.8:0.2.

The title compound, C14H12INO3S, crystallizes with two independent molecules (AandB) in the asymmetric unit. The dihedral angle between the two aryl rings is 83.1 (4)° in moleculeAand 79.8 (4)° in moleculeB. In the crystal, the two molecules are linked by a pair of N—H...O hydrogen bonds, forming anA–Bdimer with anR22(8) ring motif. The dimer is further strengthened by a pair of C—H...O hydrogen bonds with anR22(14) motif. Another pair of C—H...O interactions assembles these dimers along the diagonal of thebcplane, forming ribbons. Adjacent ribbons are connected by C—H...πarylinteractions between theAmolecules, and thus the overall supramolecular architecture is one-dimensional.

The asymmetric unit of the title compound, poly[(dimethylamine-κN)[μ3-(E)-2,6-dimethyl-4-styrylpyridine-3,5-dicarboxylato-κ3O3:O3′:O5]zinc(II)], [Zn(C17H13NO4)(C2H7N)]n, consists of one crystallographically independent distorted tetrahedral ZnIIcation, one (E)-2,6-dimethyl-4-styrylpyridine-3,5-dicarboxylate (mspda2−) ligand and one coordinated dimethylamine molecule. TwoS- andR-type chiral units are generated from the axially prochiral mspda2−ligand through C—H...O hydrogen bonds. TheR-type chiral units assemble a left-handed (M) Zn–mspda helical chain, while the right-handed (P) Zn–mspda helical chain is constructed from neighbouringS-type chiral units. TheP- andM-type helical chains are interlinked by carboxylate O atoms to form a one-dimensional ladder. Interchain N—H...O hydrogen bonds extend these one-dimensional ladders into a two-dimensional supramolecular architecture. The title compound exhibits luminescence at λmax= 432 nm upon excitation at 365 nm.
