The pursuit of robust, long-range magnetic ordering in two-dimensional (2D) materials holds immense promise for driving technological advances. However, achieving this goal remains a grand challenge due to enhanced quantum and thermal fluctuations as well chemical instability the 2D limit. While has been realized atomically thin flakes transition metal chalcogenides halides, these often suffer from air instability. In contrast, carbon-based are stable enough, yet lies creating high density local moments controlling their ordering. Here, we report novel wafer-scale synthesis an air-stable metallo-carbon nitride monolayer (MCN, denoted MN
