Thermal ammonolysis of quasi-two-dimensional (quasi-2D) yields the and anionic vacancy-ordered (), which exhibits a transition from antiferromagnetism to defect-engineered above-room-temperature ferromagnetism. First-principles calculations reveal that the origin of ferromagnetism is a particular configuration with N located at Wyckoff position , which breaks mirror symmetry about the plane. A pressure-induced electronic phase transition is also predicted at , accompanied by insulator-to-metal transition and magnetic moment vanishing.
