Heterovalent ternary nitrides are considered one of the promising classes of materials for photovoltaics, combining attractive physical properties with low toxicity and element abundance. One of the front-runner systems under consideration is ZnSnN. Although it is nominally a ternary compound, no clear crystallographic evidence for cation ordering has been observed so far. An attempt to elucidate this discrepancy [Quayle (2020). Acta Cryst. A76, 410-420] was the trigger for an intensive discussion between the authors, and an agreement was reached to elaborate on some points in order to set things in perspective. Rather than using a conventional comment-answer scheme, this is published in the form of a joint discussion to celebrate constructive criticism and collegiality.
异价三元氮化物被认为是光伏领域有前景的材料类别之一，它兼具吸引人的物理性质、低毒性和元素丰度。正在考虑的领先体系之一是ZnSnN₂。尽管它名义上是一种三元化合物，但迄今为止尚未观察到阳离子有序排列的明确晶体学证据。[奎尔（2020年）。《晶体学报》A76卷，410 - 420页]试图阐明这种差异引发了作者之间的深入讨论，并且达成了一项协议，即详细阐述一些要点以便正确看待问题。本文并非采用传统的问答形式，而是以联合讨论的形式发表，以倡导建设性批评和合作精神。
