The nuclear quadrupole interaction of 204m Pb in lead oxides has been measured by g-g time differential perturbed angular correlation. Ab-initio calculations of the electric field gradients and X-ray diffraction allowed the assignment of the detected nuclear quadrupole interactions to the different Pb sites in the PbO phases litharge and massicote as well as in Pb 3 O 4 . The TDPAC probe 204m Pb was produced with a 204 Bi/ 204m Pb-generator at the home laboratory at the University of Leipzig. The use of a high performance liquid chromatography system increased significantly the yield, the specific activity of 204m Pb, and reduced the acidic concentration of the eluate.

This paper focuses on the syntheses, structures, and luminescence properties of 1D, 2D, and 3D coordination polymers built upon the tetranuclear Cu(4) X(4) clusters and mono- and dithioether assembling ligands. A review of the relevant literature is presented along with our own results stressing on the salient features of the interactions between the CuI salt as the starting material and the thioethers. Among the features, the solvato- (lost or gain of a monothioether or solvent molecule) and luminescence thermochromism (temperature dependence of the emission) of the solids, and the enhanced versatility of the CuI salt to form clusters of different nuclearity (Cu(2) I(2) , Cu(4) I(4) , Cu(6) I(6) ) and structures (closed cubane, partially open "flower-basket-like" cubane, and open cubane) upon the reaction conditions and ligands, are described. The steady state and time-resolved solid-state emission and excitation spectra (at 298 and 77 K) as well as the emission lifetimes are examined. Simple and apparently "innocent" modification may have a drastic effect on the polymer network and cluster structures, but this paper finds no obvious trend for the moment except for the ligand rigidity. The rhombic Cu(2) I(2) and closed-cubane Cu(4) I(4) clusters are the most encountered motifs whereas the open-flower-basket Cu(4) I(4) cubane and the hexagonal Cu(6) I(6) clusters are scarce.
