Main‐group singlet biradicaloids have been thoroughly investigated in the past two decades, especially derivatives of cyclobutane‐1,3‐diyl. However, in each of the known examples, the radical centers are identical. Therefore, we sought to prepare a mixed dipnictadiazanediyls with P and As bearing the radical character. To achieve this goal, the unprecedented cyclodichloro arsaphosphadiazane [ClP(μ‐NTer) 2 AsCl] had to be prepared first. Treatment of [ClP(μ‐NTer) 2 AsCl] with a halide‐abstracting agent led to the novel cyclic cation [P(μ‐NTer) 2 AsCl] + , while reduction with magnesium afforded the first arsaphosphadiazanediyl [P(μ‐NTer) 2 As].
