Abstract - Summary
(short description): | |
| The conformation of [O2Pb3]2+ double chains of edge-sharing OPb4 oxocentered tetrahedra is discussed. The conformation can be interpreted as an adaptation of tetrahedral chains to the large halide ions (Br-, Cl-). Such conformation was previously observed for single chains of edge-sharing [XA4] anion-centred tetrahedra. This adaptation is very reminiscent of that of silicate chains to large cations (Ca, Na, REE). |
