Easy breakage to open‐shells : The diamagnetic butterfly‐like dichalcogen complexes 1 (E=Se) and 2 (E=Te) with a {Ni II 2 E 2 } core, undergo facile dissociation in solution via spin crossover to give the unprecedented mononuclear paramagnetic superselenide and supertelluride species 1′ and 2′ , respectively, along with the nickel(I) fragment [LNi I ]; R=2,6‐diisopropylphenyl.
