The ionic clusters of main group elements are called Zintl ions. Since these ions have no ligands, these are also known as naked clusters. Zintl ions are classified into closo, nido, arachno and hypho clusters. If
Total electron count (TEC) =4n+2 (closo)
TEC=4n+4 (nido)
TEC=4n+6 (arachno)
TEC=4n+8 (hypho)
where n=number of metal atoms in the Zintl ion.
