Compared to oxides the arrangement of anions in the material represents a further structural degree of freedom. The bulk oxynitride LaTiO$_2$N prefers a bonding-dominated \\textit{cis} nitrogen arrangement, while we have previously shown that the (001) surface prefers a non-polar \\textit{trans} order to compensate polarity. Here we consider, using density functional theory calculations, the polar/non-polar interface that would necessarily be present between the two anion orders.
