Question

define neutral sphere complex
​

Answer 1

Answer:

A coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.[1][2][3] Many metal-containing compounds, especially those of transition metals, are coordination complexes.[4] A coordination complex whose centre is a metal atom is called a metal complex of d block element.
