Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups…
배위화합물과 명명법
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For…
금속-리간드 결합
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain…
배위수와 기하학적 구조
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers…
구조이성질현상
Isomerism in Complexes Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can…
입체이성질현상
Isomers are different chemical species that have the same chemical formula. Transition metal complexes often exist as geometric isomers, in which…
