Interactions of Organic Nitroso Compounds with Metals

“…Only one X-ray crystal structure of a complex containing structure D in Figure (containing the bound RNO dimer) has been reported, namely, that of [Fe{[PhNO] 2 } 3 ][FeCl 4 ] 2 . , Such metal−[RNO] 2 complexes are known, however, for Sn, Ti, and Pb. − …”

“…174,175 Such metal-[RNO] 2 complexes are known, however, for Sn, Ti, and Pb. [238][239][240] (3) N,O-Binding. The attachment of both the N and O atoms of the nitroso group to metals increases the N-O bond distance (Table 7) and results in a lowering of the N-O bond order.…”

Selective modification of the metal coordination environment in heavy alkaline–earth iodide complexes

“…The nitrosobenzene dimer is a rarely encountered ligand; it has been proposed to exist in tin, 59 lead, 60 and titanium 61 complexes, but there are only two structurally authenticated examples. 40,41 In the crystal structure of azobenzene dioxide, 51 The crystallographic evidence that there is considerable NQN bond character in the dimer is supported by solid-state NMR studies.…”

A Novel Intermediate in Allylic Amination Catalyzed by Iron Salts

“…Complex 1 , {Fe[Ph(O)NN(O)Ph] 3 }[FeCl 4 ] 2 , is thus found to consist of tetrahedral Fe(III)Cl 4 - anions and a six-coordinate dication having iron(II) bound through the oxygens of three azobenzene dioxide ligands. Remarkably, while C-nitroso compounds are well known to exist as azo dioxide dimers in the solid state, 1 provides the first crystallographically established metal complex having a C-nitroso dimer (azo dioxide) ligand . The distinctly distorted, nonoctahedral cation of 1 features planar chelate rings and rather varied Fe−O (2.12 Å av) lengths, but relatively uniform O−N (1.28 Å av) and N−N (1.29 Å av) bond lengths.…”
