text: Some examples of stannide Zintl ions are listed below. Some of them contain 2-centre 2-electron bonds (2c-2e), others are "electron deficient" and bonding sometimes can be described using polyhedral skeletal electron pair theory (Wades rules) where the number of valence electrons contributed by each tin atom is considered to be 2 (the s electrons do not contribute). There are some examples of silicide and plumbide ions with similar structures, for example tetrahedral , the chain anion (Si),  and .
  *Sn found for example in MgSn.
  *, tetrahedral with 2c-2e bonds e.g. in CsSn.
  *, tetrahedral closo-cluster with  10 electrons (2n + 2).
  *(Sn) zig-zag chain polymeric anion with 2c-2e bonds found for example in BaSn.
  * closo-cluster, 12 electrons (2n + 2), (i.e. trigonal bipyramidal) in (2,2,2-crypt-Na)Sn.
  * polymeric two-dimensional anion in NaSn.
  * nido-cluster 22 electrons (2n + 4), capped square antiprismatic with  as per polyhedral skeletal electron pair theory, in the intermetallic KSn, and a distorted ion in the salt NaSn·7 en.
  * a paramagnetic, 21 electrons, closo- cluster anion (D symmetry), 1 more electron than the 20 (2n + 2) predicted by polyhedral skeletal electron pair theory.
  * polymeric two-dimensional anion in NaSn
