The analysis of atom-to-atom and/or residue-to-residue contacts remains a favoured mode analysing the molecular packing in crystals. In this contribution, additional tools are highlighted as methods for order to complement `crystallographer's tool', PLATON [Spek (2009). Acta Cryst . D 65 , 148–155]. Thus, brief outline procedures and what can be learned by using Crystal Explorer [Spackman & Jayatilaka CrystEngComm 11 19–23] is presented. Attention then directed towards evaluating nature,...
Crystalline Bi2S3 nanorods, nanotapes, and nanocrystals were obtained from the solvent thermalysis of bismuth trisxanthate precursors related dithiocarbamate species in ethylene glycol at 197 °C. Precursors with different structural motifs designed to produce compounds thermal decomposition temparatures, i.e., dimeric motif Bi(S2COR)3 when R = methyl ethyl was found have a lower temperature compared adopting polymeric structure, so that solvothermalysis former gave rise short nanocrystals;...
Abstract The uses and potential utility of tin/organotin dithiocarbamate, − S 2 CNR′ , compounds are reviewed. Various derivatives exhibit exciting as anti‐cancer agents, anti‐microbial agents insecticides, e.g. against mosquito larvae. Tin dithiocarbamates have also proven useful precursors for tin sulfide nanoparticles. There is a wealth structural data available such with the exception diorganotin bis(dithiocarbamate) compounds, R Sn(S ) which different motifs evident, there certain...
Crystal structures of transition and main group element 1,1-dithiolates are shown to be partially sustained by C–H⋯π(chelate) interactions. For the planar binary bisdithiocarbamates, C–H⋯π(MS2C) interactions lead aggregation patterns ranging from a 0-D four molecule aggregate 3-D architecture but with majority featuring 1-D or 2-D supramolecular assemblies.
A survey of the fascinating structural chemistry zinc-triad 1,1-dithiolates is presented. total twelve distinct motifs are delineated ranging from monomeric, dimeric, tetrameric, linear polymeric, layer to 3-dimensional network architectures. Such diversity arises prevalent secondary bonding interactions, i.e. A⋯S, operating in solid state. While variation structure suggests that control interactions difficult, a possible design tool for crystal engineering identified, namely by moderating...
A series of R3SnO2CR' compounds, where R = Me (1), Et (2), nBu (3), Ph (4), and cHex (5) R'CO2 is the carboxylate residue 2-[(E)-2-(2-hydroxy-5-methylphenyl)-1-diazenyl]benzoic acid, has been shown by multinuclear magnetic resonance studies to be monomeric in solution. Crystallography shows that four-coordinate species are found solid state for 4 5 but polymeric structures with five-coordinate tin atoms 1−3. The different behavior ascribed steric demands tin-bound substituents. fair...
X-ray crystallography shows the gold atoms in [R3PAu{SC(OMe)=NC6H4NO2-4}] (R = Et, Cy, Ph; 1-3, respectively) and [(Ph2P-R-PPh2){AuSC(OMe)=NC6H4NO2-4}(2)] CH2, (CH2)2, (CH2)3, (CH2)4, Fc; 4-8, are linearly coordinated by phosphorus thiolate-sulfur; weak intramolecular Au...O interactions featured all structures.

An asymmetric twistacene, 1',4'-diphenyl-naphtho-(2'.3':1.2)-pyrene-6'-nitro-7'-methyl carboxylate (tetracene 2), was synthesized by using benzyne-trapping chemistry. Its structure, determined X-ray crystallography, confirmed that this material has a twisted topology with torsion angles as high 23.8(3) degrees. Organic light-emitting devices tetracene 2 either charge-transporting materials or emitters have been fabricated. The results indicate bipolar transporting behavior in these devices.
Enantioenriched 2,3,4-trisubstituted thiochromanes have been synthesized by using a cupreine-catalyzed tandem Michael addition-Henry reaction between 2-mercaptobenzaldehydes and β-nitrostyrenes. Good diastereoselectivities enantioselectivities were obtained for the title compounds, which may be further improved through single recrystallization (up to 98% de and> 99% ee).
Two bidentate NS ligands were synthesized by the condensation reaction of S-2-methylbenzyldithiocarbazate (S2MBDTC) with 2-methoxybenzaldehyde (2MB) and 3-methoxybenzaldehyde (3MB). The reacted separately acetates Cu(II), Ni(II) Zn(II) yielding 1:2 (metal:ligand) complexes. metal complexes formed expected to have a general formula [M(NS)2] where M = Cu2+, Ni2+, Zn2+. These compounds characterized elemental analysis, molar conductivity, magnetic susceptibility various spectroscopic...

The solution-phase stabilities of 1-5 determined time-dependent NMR UV-vis, also octanol/water partition coefficients obtained...
