Abstract
The hybrid metal halide [(CH3)3NOH]2CoCl4 exhibits a first-order phase transition at T ∼ 343 K. Its crystal structure and caloric properties respond significantly to moderate pressures (1–1000 bar), demonstrating potential for applications in emerging solid-state refrigeration technologies.
