Complementary material: Data sets of predicted stable and meta-stable crystalline phase structural of Nb-N system under pressure

These files correspond to the convex hull information, individuals, input files and codes, obtained and created to analyze the stable and meta-stable crystalline phases of the Nb-N system at various pressures.本数据集的文件包含凸包（convex hull）信息、单体数据、输入文件与代码，上述内容均为分析不同压强下铌-氮（Nb-N）体系的稳定与亚稳晶相所获取及创建的。
