  Tungsten- and molybdenum-dinitrogen complexes bearing bis(dialkylphosphinobenzene)chromiums have been prepared and characterized by X-ray crystallography. Reactions of these dinitrogen complexes with an excess amount of sulfuric acid in methanol at room temperature give ammonia in good yields. Stoichiometric reactions of some dinitrogen complexes with 2 equiv of trifluoromethanesulfonic acid afford

  Reaction of mu-ethylidyne-nona(carbonyl)-tri(cobalt) (3) with (Me(2)P-eta(6)-C6H5)(eta(6)-C6H6)Cr (1) and (Me(2)P-eta(6)-C6H5)(2)Cr (2), respectively, at ambient temperature affords the substitution products [(Me(2)P-eta(6)-C6H6)(eta(6)-C6H6)Cr[(mu-CL-MeC)CO3(CO)(8)] (5), [Me(2)P-eta(6)-C6H5]Cr-2][(mu-MeC)Co-3(CO)(8)](2) (6) and [Me(2)P-eta(6)-C6H5Cr][(mu-MeC)Co-3(CO)(7)] (7). The surprisingly mild conditions under which these reactions proceed are a consequence of an electron-transfer chain (ETC) autocatalysis which operates due to the close proximity of the redox potentials 1(+/0), 2(+/0) and 3(0/-) as determined by cyclic voltammetry. In the case of 6, reduction of the two CCo3 carbonyl cluster units does not feature redox splitting, i.e. delta E(1/2) < 100 mV. EPR evidence for the ETC mechanism, which is initiated by the formation of the radical ions 1(+), 2(+) and 3(-), is also presented. Compounds 6 and 7 were subjected to X-ray diffraction analysis. 6: triclinic, P ($) over bar 1, a = 862.5(4) pm, b = 1005.7(5) pm, c = 1282.7(3) pm, alpha = 106.54(3)degrees, beta = 94.86(3)degrees, gamma = 93.52(4)degrees, Z = 1, wR = 0.073 for 2419 reflections with F > 4 sigma(F). 7: triclinic; P ($) over bar 1 a = 1047.4(2) pm, b = 1068.0(1) pm, c = 1442.4(2) pm, alpha = 90.36(1)degrees, beta = 110.34(1)degrees, gamma = 113.32(1)degrees, Z = 2, R = 0.0435 for 2241 reflections with F > 4 sigma(F).

  The binuclear radical complex 7(+) has been synthesized and studied by cyclic voltammetry; the redox couple 7(.)/7(..+) is reversible. During the course of the oxidation, the isotropic, fluid solution EPR signal of 7(.) is replaced by the rigid solution triplet EPR spectrum of 7(..+). The only intermetallic communication, detectable by EPR, consists in electron-electron spin-spin interaction in 7(..+). Its origin is essentially dipolar.
