The complex [Pt(2)Cl(2)(Spym)(4)], where Spym = 2-mercaptopyrimidine, was synthesized and analyzed spectroscopically. The presence in the (195)Pt NMR spectrum, of only one signal for the Pt(III) indicates the symmetrical arrangement of the ligands and the identical setting of N, S and Cl atoms, PtS(2)ClN(2), for the two Pt atoms being different to other compounds described in the literature. Th...

In the title complex, [Ni(C(6)H(7)N(2)S)(2)(CH(4)N(2)S)(2)], the central Ni atom (located on a centre of inversion) is six-coordinated by two monoanionic N,S-chelating 4,6-dimethyl-pyrimidine-2-thiol-ate ligands and two trans S-coordinating thio-urea groups. The trans-N(2)S(4) donor set defines a distorted octa-hedral geometry.

In the title compound, [Ru(C(5)H(4)NO)(C(10)H(8)N(2))(2)]PF(6)·0.5C(6)H(6), the Ru(2+) cation has a distorted octa-hedral RuN(5)O coordination environment. This complex is more distorted than the closely related ruthenium complex containing a pyridine-2-thiol-ate ligand [Santra et al. (1997 ▶). J. Chem. Soc. Dalton Trans. pp. 1387-1393]. The distortion is caused by the difference in size betwee...

Luminescent lanthanide complexes have unusual spectroscopic characteristics, including millisecond excited-state lifetime and sharply spiked emission spectra. These characteristics make them valuable alternatives to conventional organic fluorescent probes in detection applications and for measuring nanometer-scale conformational changes in biomolecules via resonance energy transfer. Our group h...

The reactions of 2-mercatopyrimidine with MCl(2) (M = Mn(2+) or Co(2+)) in solvothermal conditions result single crystals of Mn(2-pymS)(2)1 and Co(2-pymS)(2)2. The two complexes both have the diamond-like topology frameworks, which could be traced back to the similar way of pyrimidine rings acting as the asymmetric bridging ligands. Interestingly, although they have similar chemical formulas, s...

Water-soluble polymers have been used for a wide variety of applications due to their versatility. Watersoluble polymers are found in many different industries including agriculture, food, plastics, pulp and paper, mining, petroleum, textiles, and waste water treatment. Often, they are used as both processing aids and components of final products. Addition of water-soluble polymers to industria...
