The unusual magnetic behavior of [Ru 2 (μ‐O 2 CMe)(μ‐DPhF) 3 (H 2 O)]BF 4 ⋅0.5 CH 2 Cl 2 ( 1 ; DPhF= N , N ′‐diphenylformamidinate), which is intermediate between that of compounds with spin states S =1/2 and S =3/2, is attributed to a quantum mechanical spin admixture. This phenomenon results from a multiple bond between the metal atoms which permits an appropriate disposition of molecular orbitals.
