Coordination compounds play an essential role in the chemical industry and in our lives.; This Ziegler-Natta catalyst for this polymerization is just a complex of the metals aluminum and titanium.; (B) Hemoglobin[′hi:m?′gl??bin], which carries oxygen to animal cells, is an iron complex....
a transistor made of a bi-layer graphene nanoribbon with a band gap of ~0.16 eV shows a dramatically boosted on-off ratio of 10711. Besides the thickness control in this example, the band gap engineering of 2D materials has been widely explored by a number of chemical methods such as...
In some cases, the number of significant figures used for a particular value may be one non-limiting method of determining the extent of the word “about.” In other cases, the gradations used in a series of values may be used to determine the intended range available to the term “...
Lead (II) has a stable oxidation state of +2 with a coordination number of 6. All six PbII-X bonds of the halogen ligands, the holo-directed structures in which the ligand atoms are connected to each other, are clearly ionic, but the ionic character of the bonds decreases as the ...
