Seven organic-inorganic hybrids [(H2L1)3(Bi2Br9)(BiBr6)(H2O)] (1) (L1 = N,N,N′,N′-tetramethylethylenediamine), [(HL2)3(SbCl5)] · Cl (2) (L2 = 4-chlorobenzylamine), [(HL3)3(SbCl4)] · Cl2 (3) (L3 = 2,6-dimethylaniline), [(HL3)2(ZnCl4)] · 2H2O (4), [(HL4)4(Bi2Br10)] (5) (L4 = 2-methylquinoline), [(HL4)2(SbCl5)] (6) and [(H2L5)2(SbCl5)2] · H2O (7) (L5 = bis(N-imidazolyl)methane) were prepared and characterized by IR, XRD, EA and TG analysis. XRD analysis told that all complexes were built from non-covalent bonds between the cations and the perhalometallates anions. The lattice H2O also played crucial role in structure extension in the respective hybrids. Extensive intermolecular interactions have been used in the self-assembly of diverse motifs, ranging from strong X-H···Y (X = O, N; Y = Br, Cl, O) H-bonds to weak CH-M (M = Cl, Br), CH2-M (M = Cl, Br), CH3-M (M = O, Cl, Br), CH3-CH3/CH3-CH/CH2-CH/CH-CH, Cl-Cl, CH3-π and π-π associations. Among them, 3 D architectures are found in 1–2 and 4–7, but only 2 D motif is appeared in 3. The arrangements of the anions and cations in the solid mode are ruled not only by the size and symmetry of the cations, but also by the non-covalent bonds in the crystals. Seven organic-inorganic hybrid salts of Bi, Sb and Zn were prepared by using N-Brønsted bases in HX (Cl, Br), and their structures were characterized through X-ray diffraction. The compounds exhibit 2D sheet and 3D net. The thermal properties were also studied. [ABSTRACT FROM AUTHOR]

Eight organic-inorganic hybrid salts [(HL1)(SbCl4)] (1) (L1 = N,N-dimethylbenzylamine), [(HL2)2(ZnCl4)] (2) (L2 = 4-chlorobenzylamine), [(HL2)(L2)(CuCl3)(H2O)2] (3), [(HL3)2(Sb2OCl6)] (4) (L3 = quinoline), [(HL4)4(Bi2Cl10)] (5) (L4 = 2-methylquinoline), [(HL5)(SbCl4)] (6) (L5 = 5,7-dimethyl-1,8-naphthyridine-2-amine), [(H2L6)(SbCl5)] (7) (L6 = 3,6-bis(imidazol-1-yl)pyridazine) and [(H2L7)2(CuBr4)2] · 7H2O (8) (L7 = di(2-benzimidazol-1-ylethyl)ether) were prepared and characterized by IR, XRD, EA and TG analysis. XRD analysis told that all of the complexes were 3 D net built from non-covalent bonds from the cations and the halometallates. The aryl rings of the cations in all of the compounds are essentially planar. The H2O also had crucial role in structure extension in 3 and 8. Extensive intermolecular interactions have been used in the self-assembly of diverse motifs, ranging from strong N-H···X (X = Br, Cl), N-H···O, N-H···N, O-H···O, O-H···Br H-bonds to weak CH2···O, CH3-Cl/CH2-Cl/CH-Cl, Cl-Cl, O-Br, CH3-π, CH2-π, Cl-π and π-π associations. The arrangements of the anions and cations in the solid are ruled not only by the size and symmetry of the cations, but also by the non-covalent bonds in the crystal structures.

Transition metal carboxylates with O- and N-donor ligands are interesting for their structural features. Seven novel isonicotinamide(inic)-based metal complexes of [Cd(inic)2(L1)2(H2O)2] · 2H2O (1) (L1 = 2-chloronicotinate), [Cd(inic)2(L2)2(H2O)2] (2) (L2 = 2,4-dichlorobenzoate), [Cu(inic)2(L3)2] (3) (L3 = 4-chlorophenoxyacetate), [Cu3(inic)6(L4)2(HL4)2(H2O)2] · 2H2O (4) (L4 = azelate), [Zn(inic)2(L1)2(H2O)2] · (inic) · H2O (5), [Zn(inic)(L5)(H2O)4] (6) (L5 = 3-nitrophthalate) and [Zn2(inic)2(L6)2] · 5H2O (7) (L6 = 1,4-cyclohexanedicarboxylate) have been obtained by the introduction of the carboxylates by the common solution method and are structurally featured by different techniques of EA, IR spectra, TG and SCXRD analysis. The X-ray studies told that these complexes display mononuclear to trinuclear structures with octahedral/square-pyramidal geometry around the Zn2+, trigonal bipyramidal/octahedral at the Cu2+ and octahedral for the Cd2+. The inic in 1–7 are coordinated only in monodentate fashion with its ring N, while 5 has the lattice inic. The carboxylates coordinated to the metal in monodentate, chelating bidentate and bridging bidentate fashions. The pair of complementary N-H···O H-bonds from the CONH2 of the inic were found in all compounds except 7. Except 1 and 2, all other compounds bear the CH-O contacts from the pyridine CH of the inic. The intricate intra- and intermolecular classical H-bonds, CH-N, CH-O, CH-Cl, CH2-O, O-N, O-O, Cl-O, Cl-Cl, CH-π, CH2-π, C-π, N-π, Cl-π and π-π associations are elucidated by the X-ray crystallographic studies, which push the discrete complexes into high-dimensional ordered supramolecular structures.
