What is Coordination compounds: Definition and 46 Discussions

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. Many metal-containing compounds, especially those of transition metals (d block elements), are coordination complexes.

    D2sp3 and sp3d2 Configurations of [Cr(NH3)6]3+ Ligand Complex

    [Cr(NH3)6]3+ has Cr3+ ion and the ligand is weak field. Hence the configuration of Cr ion is 3d3,4s0 My doubt is,will the ligands donate electrons starting from 3d to form d2sp3 or will it start from 4s and use 4p and 4d to form sp3d2? I know the 3 electrons of chromium are still unpaired but...
