Synthesis Properties

Tetra(n-butyl)ammonium nitrite reacts with ‘dichlorophthalocyaninatoruthenium(III) acid’ to yield bis(tetra(n-butyl)ammonium) bisnitrophthalocyaninatoruthenate(II). It crystallizes monoclinic with crystal data: a = 15.114(4) Å, b = 22.34(3) Å, c = 18.206 (11) Å, β = 90.88(5)°; space group P1 21/n 1, Z = 4, and its X-ray crystal structure has been determined. Ru is located in the centre of the slightly distorted phthalocyaninate dianion, and is coordinated to two nitrite ions through their nitrogen (N) atoms in a staggered trans-configuration. The average Ru - N p ( Np pyrrolic N atoms) and Ru -N distance is 1.978(6) and 2.068(5) Å, respectively. The electrochemical and spectroscopic properties (IR, resonance Raman, UV/vis) of the compound are in full agreement with its molecular structure.

Abstract The reaction of the phosphido-bridged metal carbonyl [FeRh(CO)6(μ-PBut2)] (1) with dppm [dppm = bis(diphenylphosphino)methane] leads to the heterobimetallic complex [FeRh(μ-CO)(CO)3(μ-PBut2)(μ-dppm)] (2) in good yields. The molecular structure of 2 was determined at room temperature [triclinic, space group P1̄, a = 9.509(6), b = 13.637(5), c = 14.926(8) Å, α = 81.38(4), β = 82.75(4), γ = 71.25(4)°].

AbstractThe thionitrosyl-halothionitrene com pounds (PPh4)2[ReX4(NS)(NSX)]·2 CH2X2, X = Cl or Br, are obtained by nucleophilic ring cleavage of the Re(N2S2) rings of complexes [ReX4(N2S2)]⊖ with PPh4X in CH2X2. (AsPh4)2[ReCl4(NS)(NSCl)] · CH2Cl2 can also be obtained by the reaction of [ReCl4(NSCl)(POCl3)] with S(NSiMe3)2 and subsequent addition of AsPh4Cl. The pyridine complex [ReBr2(NS)(NSBr)(NC5H5)2] · CH2Br2 forms by bromination of the corresponding chloro compound with Me3SiBr. The IR spectra are reported. The crystal structure of (PPh4)2[ReBr4(NS)(NSBr)] · CH2Br2 was determ ined by X-ray diffraction (4158 independent observed reflexions, R = 0.059). Crystal data: a = 1039.7, b - 1232.5, c - 2158.4 pm, α = 81.59, β = 87.05, γ = 77.06°, Z = 2, space group P1̄. The compound consists of PPh4⊕ ions, CH2Br2 molecules, and anions [ReBr4(NS)(NSBr)]2⊖ in which the rhenium atoms are coordinated by four bromine atoms, one thionitrosyl and one brom othionitrene group. The latter have cis arrangement and ReN bond lengths of 186 pm. W hereas the thionitrosyl group is nearly linear, the R = N = SBr group has an ReNS angle of 165°.

The complex has a molecular structure. Neutral phosphoryltriamide ligands are coordinated to the metal ion in a bidentate manner via phosphoryl and carbonyl oxygen atoms with formation of six membered chelate rings. The coordination polyhedron of the Ce atom is a sphenocorona; C.N. = 10 (4 O[HL] + 6 O [NO3-]).
