On the reactivity of F(3)S[Triple Bond]NXeF(+): syntheses and structural characterizations of [F(4)S=N-Xe---N[Triple Bond]SF(3)][AsF(6)], a rare example of a N-Xe-N linkage, and [F(3)S(N[Triple Bond]SF(3))(2)][AsF(6)].
Inorganic Chemistry, 2009Co-Authors: Gregory L. Smith, Gary J. SchrobilgenAbstract:The F(4)S=N-Xe---N[Triple Bond]SF(3)(+) cation has been synthesized as the AsF(6)(-) salt by rearrangement of [F(3)S[Triple Bond]NXeF][AsF(6)] in N[Triple Bond]SF(3) solvent at 0 degrees C. Deep yellow [F(4)S=N-Xe---N[Triple Bond]SF(3)][AsF(6)], which crystallized from a N[Triple Bond]SF(3) solution at -10 degrees C, was characterized by Raman spectroscopy (-160 degrees C) and by single-crystal X-ray diffraction (-173 degrees C). The Xe-N Bond length (2.079(3) A) of the F(4)S=N-Xe---N[Triple Bond]SF(3)(+) cation is among the shortest Xe-N Bonds presently known. The F(4)S=NXe(+) cation interacts with N[Triple Bond]SF(3) by means of a Xe---N donor-acceptor Bond (2.583(3) A) that is significantly longer than the primary Xe-N Bond (2.079(3)A) but significantly shorter than the sum of the Xe and N van der Waals radii (3.71 A). The F(4)S=N-Xe---N[Triple Bond]SF(3)(+) cation undergoes a redox decomposition in N[Triple Bond]SF(3) at 0 degrees C, forming [F(3)S(N[Triple Bond]SF(3))(2)][AsF(6)], cis-N(2)F(2), and Xe, which were characterized by low-temperature Raman spectroscopy in the solid state and by (19)F NMR spectroscopy in N[Triple Bond]SF(3) solvent (0 degrees C). Colorless [F(3)S(N[Triple Bond]SF(3))(2)][AsF(6)] crystallized from N[Triple Bond]SF(3) at -10 degrees C and was characterized by low-temperature, single-crystal X-ray diffraction. The S(IV) atom of F(3)S(N[Triple Bond]SF(3))(2)(+) has long contacts with the N atoms of two N[Triple Bond]SF(3) molecules and a F ligand of a neighboring AsF(6)(-) anion. The arrangement of long contacts avoids, to the maximum extent, the F atoms of SF(3)(+) and the nonBonding electron pair situated on the pseudo-3-fold axis opposite the F ligands of SF(3)(+), providing distorted octahedral coordination about the S(IV) atom. Quantum-chemical calculations using MP2, B3LYP, and PBE1PBE methods were employed to arrive at the gas-phase geometries, charges, Bond orders, valencies, and vibrational frequencies for F(4)S=N-Xe---N[Triple Bond]SF(3)(+) and F(3)S(N[Triple Bond]SF(3))(2)(+) to aid in the assignments of experimental vibrational frequencies. The F(4)S=N-Xe---N[Triple Bond]SF(3)(+) cation expands the known chemistry of the F(4)S=N- group and is the first example of a N-Xe-N linkage to be structurally characterized by single-crystal X-ray diffraction.

Antimony–Tungsten Triple Bond: A Stable Complex with a Terminal Antimony Ligand
Angewandte Chemie International Edition, 2005Co-Authors: Gábor Balázs, Marek Sierka, Manfred ScheerAbstract:The intermediately generated Li[(Me3Si)2CHSb(H)] reacts with [(N3N)WCl] to give the first complex with a terminal stibido ligand, [(N3N)WSb] (see structure). Spectroscopic features and the X-ray structure of this product clearly reveal the Triple-Bond character of the WSb Bond. A comparison of the Bonding situations in the series [(N3N)WE] (E=P, As, Sb, Bi) indicates only a weak polarization of the Triple Bond

complexes with a metal phosphorus Triple Bond
Topics in Current Chemistry, 2004Co-Authors: Brian P Johnson, Gábor Balázs, Manfred ScheerAbstract:A survey of the existing complexes containing a transition metal-phosphorus Triple Bond is presented. Based on the different types of these complexes—terminal and asymmetrically bridged complexes with a phosphido ligand as well as the linearly coordinated phosphinidene complexes—their characteristic structural and Bonding features as well as trends in their NMR data are discussed and compared. The present knowledge of the reactivity pattern of these types of compounds is summarized, which represents a field with tremendous perspectives.
