Abstract Growth of AlxGa1−xN layers (0 ≤ x ≤ 1) simultaneously on polar (0001), semipolar ($$10\bar{{\rm{1}}}$$ 10 1 ¯ 3) and ($$11\bar{{\rm{2}}}2$$ 11 2 ¯ 2 ), as well as nonpolar ($$10\bar{{\rm{1}}}0$$ 10 1 ¯ 0 ) and ($$11\bar{{\rm{2}}}0$$ 11 2 ¯ 0 ) AlN templates, which were grown on planar sapphire substrates, has been investigated by metal-organic vapour phase epitaxy. By taking into account anisotropic in-plane strain of semi- and non-polar layers, their aluminium incorporation has been determined by x-ray diffraction analysis. Optical emission energy of the layers was obtained from room-temperature photoluminescence spectra, and their effective bandgap energy was estimated from room-temperature pseudo-dielectric functions. Both x-ray diffraction and optical data consistently show that aluminium incorporation is comparable on the polar, semi- and non-polar planes.

A novel one-dimensional metal-organic coordination polymer, [Zn (NH3)2(BDC)]n (BDC=1,4-benzenedicaboxylate), has been synthesized by solvent evaporation method through self-assembly of Zn (II) salts with terephthalic acid ligand in ammonia aqueous solution. Single crystal X-ray diffraction analysis indicated that each Zn (II) was coordinated by two nitrogen donors from two NH3 and two oxygen counter donors from terephthalic acid ligand. The adjacent zigzag chains are arranged in a parallel fashion and linked by interchain hydrogen bonding interaction and π-π stacking interactions into higher-dimensional framework. The compound has also been characterized by CHN elemental analyses, Single crystal X-ray diffraction analysis, powder X-ray diffraction (PXRD) analysis, Fourier transform infrared (FT-IR) spectra, Thermalgravimetric-differential scanning calorimetric (TG-DSC) and Solid-state nuclear magnetic resonance (NMR), etc. Results showed that the framework of compound was stable at the temperature up to 246°C. The desolvated product [Zn (BDC)]n, which was obtained by removal of molecular NH3 from [Zn (NH3)2(BDC)]n, can be transferred to the different skeleton structures through coordinating different small hydrogen-bond-forming molecules.

AbstractTwo new metal-organic frameworks, namely, [Cd(L)(H2O)]n (1) and {[Cd0.5(L)(4,4′-bipy)0.5][Cd0.5(H2O)(4,4′-bipy)0.5]·H2O}n (2), where H2L = N-pyrazinesulfonyl-glycine and 4,4′-bipy = 4,4′-bipyridine, have been synthesized and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental, thermogravimetric, and photoluminescent analysis. X-ray diffraction crystallographic analyses indicate that 1 displays a distorted octahedral metal coordination in a 3-connected (4, 82) topology, while the molecular structure of 2 has a 4-connected (4, 4) topology with two perfectly octahedrally coordinated Cd centers. The L2– ligand serves as a N,N,O-tridentate, μ2-pyrazine-bridging, and μ2-carboxylate-bridging ligand in 1, and as a N,O-bidentate and μ2-carboxylate-bridging ligand in 2. In the crystal, a 3D supramolecular architecture is formed by O–H···O hydrogen bond interactions in 1, but through O–H···O as well as π···π stacking in 2. The two compounds show intense fluorescence in the solid state at room temperature.

We successfully synthesized two new metal coordination polymers [Cd3(bdc)3(L)3(H2O)3]n (1) and [Co(tda)(L)]n (2) (H2bdc = 1,2-benzenedicarboxylic acid, H2tda = 2,5-thiophendicarboxylic acid, and L = 3,5-bis(benzimidazol-1-yl)pyridine), which were then characterized by IR, and elemental, X-ray powder diffraction, and X-ray single-crystal diffraction analysis. Complex 1 possesses a uninodal three-connected hcb Shubnikov hexagonal plane net with {63} topology. Complex 2 features a three-connected topological net with {82·10} topology (so-called ‘tongue-and-groove’ structure). A typical T-shaped molecular bilayer motif, which has rarely been reported previously, was successfully constructed by strategically selecting H2tda as the second ligand. In addition, the solid-state photoluminescent spectra of 1 and 2 were measured at room temperature.
