Complexes of Divalent Tellurium with Ethylenethiourea.

Divalent ytterbium complexes with crown and heterocrown ethers.

Several unusual complexes of ytterbium(ii) stabilised by coordination to mixed O4X2-donor macrocyclic ligands (X = O, NH, S or Se) are described. Distorted 8-coordination is evident from the crystal structure of the neutral [YbI2([18]aneO4Se2)], forming the first reported example of Yb(ii)-selenoether coordination.

Targeting divalent metal cations with Re(I) tetrazolato complexes.

In order to exploit their potential as versatile luminescent sensors, four new Re(I)-tetrazolato complexes with the general formula fac-[Re(CO)3(diim)(L)], where diim is 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) and L(-) is either the anion 5-(2'-pyridyl)tetrazolato (2-PTZ(-)) or 5-(2'-quinolyl)tetrazolato (2-QTZ(-)), were prepared and fully characterized. In all cases, the regiosele...

Spin-birefringence in molecular currents: Tellurium and gold complexes

We simulate the spin-flip current and transmission function through rings containing elements with a spin–orbit interaction. In a previous study (J. Chem. Phys. 123 (2005) 204714) we predicted that such a system can show spin-birefringence, i.e., a spin current polarized parallel to the molecular axis can flip its direction due to a phase lag due to the spin–orbit interaction. Here we demonstra...

Analgesic Activities of Synthesized Divalent Metal Complexes of Tolfenamic Acid

The objective of the study was to synthesize and to uncover the potentially interesting biological peripheral and central analgesic activities of some new divalent metal complexes of tolfenamic acid. The inception of the study was carried out with the formation of complexes [Cu(tolf)2(H2O)]2, [Co(tolf)2(H2O)2] and [Zn(tolf)2(H2O)] through the reaction of tolfenamic acid, a potent anti-inflammat...
