A new bi-capped Keggin heteropoly molybdovanadated derivative, [Co (en)3]2[SiMo8V6O42]∙6H2O (1) (en = ethylendiamine) has been hydrothermally synthesized and structurally characterized by the elemental analysis, IR, XPS and single crystal X-ray diffraction. The crystal structure analysis reveals that compound 1 consists of [Co (en)3]2+transition metal coordination fragment and the [SiMo8V6O42]4-building blocks, which are linked together via hydrogen-bonding interactions to form a new 3-D supramolecular networks.

This work is focused on the synthesis and structure characterization of the novel Cu(I) π-complex [Cu2(Thiaz1)2(ClO4)2] (1) with 2-allylamino-5-methyl-1,3,4-thiadiazole (Thiaz1) ligand. The crystals of the compound were obtained by means of the alternating-current electrochemical technique and studied using single crystal X-ray diffraction. The crystal structure of the complex 1 is constructed from the centrosymmetric dimers, in which two copper(I) ions are coordinated by two Thiaz1 molecules through thiadiazole N atoms and allylic C=C bond. Energy framework computational analysis for structure 1 has been performed.

Tetronic Acid

The synthesis and characterization of two new tetronic acid zinc (II) complexes of the empirical formulae [Zn(L–H)2(H2O)2] (1) and [Zn(L–H)2(H2O)(MeOH)]H2O(2) found within the same crystal are reported. The zinc ions bind through alkoxide and carbonyl groups of the ligand 3-methoxycarbonyl-5-phenyl tetronic acid (LH) as indicated byHNMR and X-ray crystallographic studies. These complexes promote intra- and intermolecular interactions, such as hydrogen bonding andπstacking, giving place to the formation of molecular aggregates.

A pair of enantiomerically pure metallodimers containing two deeply concave tribenzotriquinacene (TBTQ) units linked by a platinum-diacetylene unit were synthesized. Such linear metal-centered TBTQ dimers are considered as edges of metallosquares and metallocubes that bear four or eight mutually syn-oriented TBTQ bowls at their tips, respectively. The structures of the metallodimers were characterized by 1H, 13C and 31P NMR spectroscopy, ESI mass spectrometry, and circular dichroism. The single X-ray crystal structure of (+)-enantiomer confirmed the absolute configuration of the metallodimers and revealed an edge (tip-to-tip) length of 18.456 Å and an approximated syn-orientation of the two TBTQ bowls in the solid state.

The crystals of 4,4-diaminodiphenyl sulfoxide have been obtained by evaporation from ethanol solution. The crystal structure of the 4,4-diaminodiphenyl sulfoxide was determined by X-ray single crystal diffraction analysis. The crystal data for 4,4-diaminodiphenyl sulfoxide: monoclinic, space groupP2(1)/c,a= 49.068(10) Å,b= 11.439(2) Å,c= 13.103(3) Å,V= 7347(3) Å3,Z= 24,Mr= 248.30,De= 1.347 g/cm3,T= 298(2) K,F(000) = 3120,R= 0.0786 andwR =0.2653. The compound forms three-dimensional network structure through hydrogen bonds and π-π interaction.

In this report, we presented the usage of Stober method to fabricate SiO2 nanospheres and self-assembly method to make SiO2 opal photonic crystals based on the fabricated SiO2 nanospheres. An averaged size of SiO2 nanospheres was controlled by varying concentrations of NH4OH and TEOS. Crystal structure and morphology of particles was investigated by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Experimental results showed that SiO2 nanospheres possess amorphous crystal structure with sizes ranged from 150 to 300 nm. The diffuse reflection spectra show the reflection peaks of the SiO2 opal photonic crystals from 410 nm to 520 nm.
