The structure of the 1:2 co-crystalline adduct C8H16N4·2C6H5BrO, (I), from the solid-state reaction of 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane (TATD) and 4-bromophenol, has been determined. The asymmetric unit of the title co-crystalline adduct comprises a half molecule of aminal cage polyamine plus a 4-bromophenol molecule. A twofold rotation axis generates the other half of the adduct. The primary inter-species association in the title compound is through two intermolecular O—H...N hydrogen bonds. In the crystal, the adducts are linked by weak non-conventional C—H...O and C—H...Br hydrogen bonds, giving a two-dimensional supramolecular structure parallel to thebcplane.

The 1H and 13C spectra of mikanokryptin are unambiguously assigned using a variety of one-dimensional nmr experiments (selective homonuclear decoupling, use of inversion–recovery pulse sequences to reveal hidden peaks, and DEPT spectral editing) in conjunction with normal and "long range" two-dimensional heteronuclear correlated experiments. Detailed comparison of vicinal, allylic, and homoallylic 1H—1H coupling constants with dihedral angles determined from an earlier crystal structure determination indicates that solution and solid state configurations are similar.

The Zn2+, Cd2+, Hg2+, Co2+ and Ni2+ ions produce zwitterionic type complexes with the ligands (L), 2-(α-hydroxy-benzyl)thiamine=HBT and 2-(α-hydroxy-cyclohexyl-methyl)thiamine = HCMT, of the type MLCl3. The ligands are in the S conformation, the metals are bound to N1, of the pyrimidine moiety of thiamine and the complexes have a trigonally distorted tetrahedral structure, as the crystal structure of the complex Zn(HCMT)Cl3 (orthorombic, a=14.4 b=14.1 c=17.4 β=105.6O V=3392A3 R=13.8%), the one and two dimensional H1 nmr spectra of the Zn2+, Cd2+ and Hg2+ complexes and the electronic spectra of the Co2+ and Ni2+ complexes show. A brief review of the previous techniques (structure of the Hg(HBT)Cl3 complex, IR-Raman spectra, C13 nmr in solution and solid state etc) used to characterize these complexes, is also given here and the proper conclusions drawn.

The Mean

The molecule of the title Schiff base, C8H8BrN3OS·C2H6OS, which crystallizes as a dimethyl sulfoxide (DMSO) monosolvate, displays an E configuration with respect to the C=N bond, with a dihedral angle of 14.54 (11)° between the benzene ring and the mean plane of the N—N—C(N)=S unit. In the crystal, molecules are linked by N—H...O hydrogen bonds, forming chains propagating along the b-axis direction. Within the chains there are R 2 3(11) ring motifs, which are reinforced by C—H...ODMSO hydrogen bonds enclosing secondary R 1 2(6) and R 2 3(9) loops. The chains are linked by O—Hhydroxyl...S hydrogen bonds, forming layers parallel to (011). Inversion-related layers are linked by short Br...Br interactions [3.5585 (5) Å], forming slabs parallel to (011). The intermolecular interactions have been investigated using Hirshfeld surface studies and two-dimensional fingerprint plots. The crystal structure of the unsolvated form of the title compound has been reported previously [Kargar et al. (2010). Acta Cryst. E66, o2999], and its solid-state structure is compared with that of the title solvated form.

AbstractA new Cd(II) coordination polymer, [Cd(CNA)]n (1) (H2CNA = 3-(carboxymethoxy)-2-naphthoic acid), was hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. The crystals are monoclinic, space group P21/c with a = 16.9698(18), b = 7.8314(8), c = 8.9553(10) Å, β = 100.657(2)°, V = 1169.6(2) Å3, Z = 4, Dcalcd. = 2.03 g cm−3, μ(MoKα) = 1.9 mm−1, F(000) = 696 e, R = 0.0305, wR = 0.0784 for 172 refined parameters and 2285 data. Each CNA anion bridges three Cd(II) cations to give rise to a two-dimensional network structure. Topologically, if each CNA anion is regarded as a linker, and each Cd(II) atom considered as a 4-conencted node, the structure is simplified as a 4-connected (4,4) network. The solid state photoluminescent properties of the compound were also studied at room temperature.
