Five copper coordination complexes 1-5 with 2-bppm (2-bppm = bis(4-(pyridin-2-yl)pyrimidin-2-ylthio)methane) have been prepared and structurally elucidated. Complexes 1 and 2 are both discrete dinuclear [2 + 2] macrocyclic structures, simultaneously formed in one-pot reaction with Cu(NO 3) 2 with in situ reduction of Cu 2+. Similarly, dinuclear [2 + 2] macrocyclic motifs are found with 3 and 4, which are also obtained by one-pot reaction but with CuCl accompanied by in situ air oxidation of Cu +. Compound 5 exhibits a 1-D chain structure with 2-bppm and Cu2I2 connected one by one. Luminescence is measured for 2, 4, and 5, all based on d 10-closed shell Cu(I). © 2012 Taylor & Francis. Source

Assembly of di[4-(pyridin-3-yl)pyrimidinyl]- disulfide (3-ppds) with different metal salts resulted in a variety of coordination polymers that were structurally elucidated. For MnCI 2, a 1-D repeated rhomboidal chain structure [MnCI 2(3-ppds) 2] n (1) was obtained, whereas a 1-D helical chain structure [Zn(NO 3) 2(3-ppds)] n (2) was built from Zn(NO 3) 2. A 1-D zigzag chain structure [Cu 2- (OAc) 4(3-ppds)] n (3) was produced from Cu(OAc) 2. In all three complexes, the 3-ppds ligand plays the same role as a bis(monodentate) bridging linker but with variations in both C-S-S-C torsion angles and dihedral angles defined by its conjugated heteroaromatic rings (pyrimidine and pyridine). The luminescence properties of the complexes have been evaluated in the solid state. © Springer Science+Business Media B.V. 2012. Source

This review outlines three types of in situ methods used for constructing metal-organic sulfur-containing heterocycle frameworks, viz., in situ S-S function reactions, in situ C-S bond cleavage and in situ thiol-S atom reactions. Each method is described in detail in three respects, namely (i) reaction parameters, (ii) the organic transformation and coordination modes involved, and (iii) fascinating structures and functional properties of those in situ-generated metal-coordination compounds. © 2010 Elsevier B.V.

Multicolor electrochemiluminescence (ECL) of semiconductor nanocrystals tuned by size effect has been successfully achieved using quantum dots (QDs) with core-shell structure for the first time. It would open a new way and provide a guidance for design and preparation of stable and strong multicolor ECL emitters for simultaneous multicomponent analysis application. © 2016 Science China Press and Springer-Verlag Berlin Heidelberg Source

The self-assembly of 4-MTPP [4-MTPP = 2-(methylthio)-4-(pyridin-4-yl) pyrimidine] with Cu(NO3)2 and AgNO3 was structurally investigated. For Cu(NO3)2, a discrete mononuclear CuII coordination compound, [Cu(4-MTPP) 2(NO3)2] (1), resulted that is exclusively based on Cu-N coordination. For AgNO3, a unique one-dimensional double-chain structure (2) was obtained with the Ag-N distances varying from 2.181(9) to 2.223(9) Å, and the average Ag-S distance being 2.98 Å. Compared to zero-dimensional 1, the extension to one-dimensional 2 is considered to result from the specific affinity between Ag+ and the ligand 4-MTPP that is attributed to the strong coordinating tendency of silver for aromatic nitrogen and thioether sulfur atoms.
