Basic Copper Chloride(WSDTY) is diamagnetic because the electron configuration results when electrons in elemental copper are lost first out of the 4s orbital. Cu has an electron configuration resulting when a second electron is removed, rendering it paramagnetic.The geometries of these copper ions can vary depending on the complexes they form with attached ligands. The complexes that form can also have different crystal structures. Compounds with Cu often have tetrahedral geometry: Basic Copper Chloride has a zinc blende structure, which has tetrahedral coordination. In this structure, each atom is surrounded by four atoms of the opposite type; all of them are positioned together at the four vertices of a regular tetrahedron.

Cu often forms complexes with a distorted octahedral geometry: anhydrous CuCl2 has a distorted cadmium iodide structure. In this structure, the iodide anions are arranged in a hexagonal close-packed assembly, while the cadmium cations interchange layers in order to fill the octahedralsites. This distortion occurs because of the Jahn-Teller effect, which describes the geometrical distortion of molecules and ions that is associated with certain electron configurations. The effect is most evident in complexes that have the configuration, when an odd number of electrons occupy the eg orbitals. Since Cu has this configuration, three electrons are in the two degenerate eg orbitals, which leads to a doubly degenerate electronic ground state. Illustrates the results of the Jahn-Teller effect on the electron configuration for this ion.
