$XeF _4, SF _4, SiF _4 . BF _4^{--}, BrF _4^{-},\left[ Cu \left( NH _3\right)_4\right]^{2+},\left[ FeCl _4\right]^{2-},\left[ CoCl _4\right]^{2-}$ and $\left[ PtCl _4\right]^{2-}$.
Defining shape on the basis of the location of $X$ and $Z$ atoms, the total number of species having a square planar shape is

$2H_2O(g) \rightleftharpoons 2H_2(g) + O_2(g); K_1 = 2.1 \times 10^{-13}$
$2CO_2(g) \rightleftharpoons 2CO(g) + O_2(g); K_2 = 1.4 \times 10^{-12}$
