An example is coordination of metal ions by sugars (44). The cyclic polyol cts-inositol can coordinate metal ions in two distinct ways (Fig. 14) (45). In ax-ax-ax bonding (Fig. 14), the metal ion is part of three fused ...
WebbIn plants, water flows are the major driving force behind growth and play a crucial role in the life cycle. To study hydrodynamics, methods based on tracking small particles inside water flows attend a special place. Thanks to these tools, it is possible to obtain information about the dynamics of the spatial distribution of the flux characteristics. In … WebbChelate effect represents the stabilization of coordination compounds due to formation of metal chelates. Complexes containing chelating ligands are more stable than complexes containing unidentate ligands. Thus, [Co(en)3] 3+ is more stable than [Co(NH 3) 6] 3+. Here, en is ethylene diammine, a bidentate ligand.
