For transition metals with a coordination number of four, two different geometries are possible: tetrahedral or square planar. Unlike main group elements, where these geometries can be predicted from VSEPR theory, a more detailed discussion of transition metal orbitals (discussed in the section on Cr...
What are Transition Metals? The modern periodic metal was formed by a scientist named Dmitri Mendeleev. He arranged the elements on the periodic table by increasing atomic weight. The elements found in the same column are in the same group, while the elements found in the same row are in ...

0D TMC materials refer to structures with all dimensions being in the range of 1 ~ 100 nm, which typically consist of transition metals from Group IB to Group IIB and chalcogens, with a composition ratio of M:X ranging from 1:1 to 1:2 [43,44,45]. Their unique physical and che...
1,2,3. Moreover, the direct (or unsupported) metal–metal bonds between f-block and d-block elements in the compounds are of great interest in terms of bonding theory. Tremendous effort has been devoted to preparation of coordination compounds involving both Ln metals and TMs by wet ...
The general formula for MXenes is expressed as Mn+1XnTx, (n = 1–4), where M represents transition metals (like titanium or zirconium), n indicates the number of transition metal layers, X refers to non-metallic elements (carbon and/or nitrogen), and T denotes surface terminations such ...
The second nearest-neighbor modified embedded atom method (MEAM) [Phys. Rev. B 62, 8564 (2000)], developed in order to solve problems of the original first nearest-neighbor MEAM on bcc metals, has now been applied to all bcc transition metals, Fe, Cr, Mo, W, V, Nb, and Ta. The ...
