配合物[Fe2(mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2) (NP(pip)(3))(2)) [Co-2(mu(2)-NP(pip)(3))(2)(NP(pip)(3))（2)] (1- co)）的反应，其中[NP(pip)(3)](1) -是三（哌啶基）亚胺磷烷，与氧化亚氮，S-8或Se-0产生发散性反应。在氧化亚氮的作用下，1-Fe形成[Fe-2(mu(2)-O) (mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2)] (2- fe)，其中Fe3+-Fe3+的距离很短。1- fe与S-8或Se-0的反应导致配合物[Fe-2(mu-kappa(1): kappa(1)-E-2)(mu(2)-NP(pip)(3))(2))(NP(pip)(3))(2))(E = S, 3- fe，或Se， 4-Fe]中重硫原的桥接，侧对配位（mu-kappa(1): kappa(1)-E-2)）。在所有情况下，络合物1-Co都是惰性的。
Reaction of the complexes [Fe2(mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2)] (1-Fe) and [Co-2(mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2)] (1-Co), where [NP(pip)(3)](1) - is tris(piperidinyl)imidophosphorane, with nitrous oxide, S-8, or Se-0 results in divergent reactivity. With nitrous oxide, 1-Fe forms [Fe-2(mu(2)-O) (mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2)] (2-Fe), with a very short Fe3+-Fe3+ distance. Reactions of 1-Fe with S-8 or Se-0 result in the bridging, side-on coordination (mu-kappa(1): kappa(1)-E-2(2 -)) of the heavy chalcogens in complexes [Fe-2(mu-kappa(1): kappa(1)-E-2)(mu(2)-NP(pip)(3))(2)(NP(pip)(3))(2)] (E = S, 3-Fe, or Se, 4-Fe). In all cases, the complex 1-Co is inert.
