- The coordination polyhedron around the Pb atom in the title compound, poly[aqualead(II)-mu(5)-oxydiacetato], [Pb(mu(5)-C4H4O5)(H2O)](n), is a distorted square antiprism formed by three O atoms from one oxydiacetate ligand, four O atoms from four other identical ligands and one water O atom, resulting in a three-dimensional network structure. The almost planar oxydiacetate ligand is disordered over two positions. The Pb lone-pair 6s(2) electrons show stereochemical activity in the coordination sphere.

Tidskriftsartikel (refereegranskat)abstract
- In the late 90s critical debate and research on the media have gained wide attention. Media criticism and critique is becoming a central political, social and scientific issue. In the article the concept of media criticism is discussed. Media criticism is interpreted as public discourse assessing the media and media impact. Beyond a dialogue on media policy and media practice, criticism offers highly polarized and partly mystifying accounts of the media and its social and cultural impact. The heated debate on media is interpreted as part of a social struggle between different social institutions (markets, politics, science and media) and as different models for action and knowledge. New forms and arenas for media criticism are also suggested and discussed.
