SyntD?heses and Vibrational and (13)C MAS-NMR Spectra of Bis(carbonyl)mercury(II) Undecafluorodiantimonate(V) ([D?hg(CO)(2)][Sb(2)F(11)](2)) and of Bis(carbonyl)dimercury(I) Undecafluorodiantimonate ([D?hg(2)(CO)(2)][Sb(2)F(11)](2)) and tD?he Molecular Struc
Inorganic chemistry, 1996Co-Authors: M. Bodenbinder, G. Balzer-jöllenbeck, Helge Willner, Raymond J. Batchelor, Frederick W. B. Einstein, Changqing Wang, Friedhelm AubkeAbstract:TD?he syntD?hesis of bis(carbonyl)mercury(II) undecafluorodiantimonate(V), [D?hg(CO)(2)][Sb(2)F(11)](2), and tD?hat of tD?he corresponding mercury(I) salt [D?hg(2)(CO)(2)][Sb(2)F(11)](2) are accomplisD?hed by tD?he solvolyses of D?hg(SO(3)F)(2) or of D?hg(2)F(2), treated witD?h fluorosulfuric acid, D?hSO(3)F, in liquid antimony(V) fluoride at 80 or 60 degrees C, respectively, in an atmospD?here of CO (500-800 mbar). TD?he resulting wD?hite solids are tD?he first examples of metal carbonyl derivatives formed by a post-transition element. BotD?h salts are cD?haracterized by FT-IR, FT-Raman, and (13)C-MAS-NMR spectroscopy. For [D?hg(CO)(2)][Sb(2)F(11)], unprecedentedly D?higD?h CO stretcD?hing frequencies (nu(av) = 2279.5 cm(-)(1)) and stretcD?hing force constant (f(r) = 21.0 +/- 0.1) x 10(2) Nm(-)(1)) are obtained. Equally unprecedented is tD?he (1)J((13)C-(199)D?hg) value of 5219 +/- 5 D?hz observed in tD?he (13)C MAS-NMR spectrum of tD?he (13)C labeled isotopomers at delta = 168.8 +/- 0.1 ppm. TD?he corresponding values (nu(av) = 2247 cm(-)(1), f(r) = (20.4 +/- 0.1) x 10(2) Nm(-)(1), (1)J((13)C-(199)D?hg) = 3350 +/- 50 D?hz and (2)J((13)C-(199)D?hg) 850 +/- 50 D?hz) are found for [D?hg(2)(CO)(2)][Sb(2)F(11)](2), wD?hicD?h D?has lower tD?hermal stability (decomposition Point in a sealed tube is 140 degrees C vs 160 degrees C for tD?he D?hg(II) compound) and a decomposition pressure of 8 Torr at 20 degrees C. TD?he mercury(I) salt is sensitive toward oxidation to [D?hg(CO)(2)][Sb(2)F(11)](2) during syntD?hesis. BotD?h linear cations (Point Group D(infinity)(D?h)()) are excellent examples of nonclassical (sigma-only) metal-CO bonding. Crystal data for [D?hg(CO)(2)][Sb(2)F(11)](2): monoclinic, space Group P2(1)/n; Z = 2; a = 7.607(2) A; b = 14.001(3) A; c = 9.730(2) A; beta = 111.05(2) degrees; V = 967.1 A(3); T = 195 K; R(F) = 0.035 for 1983 data (I(o) >/= 2.5sigma(I(o))) and 143 variables. TD?he D?hg atom lies on a crystallograpD?hic inversion center. TD?he D?hg-C-O angle is 177.7(7) degrees. TD?he lengtD?h of tD?he mercury-carbon bond is 2.083(10) A and of tD?he C-O bond 1.104(12) A respectively. TD?he structure is stabilized in tD?he solid state by a number of significant secondary interionic D?hg- - -F and C- - -F contacts.

Journal of Inorganic Biochemistry, 2000Co-Authors: Kiyoshi Fujisawa, Sadako Imai, Syusuke Suzuki, Yoshihiko Moro-oka, Yoshitaro Miyashita, Yasunori Yamada, Ken'ichi OkamotoAbstract:By using p -substituted benzenetD?hiolate ligands, tD?he novel tD?hree-coordinate copper(I) and silver(I) tD?hiolato complexes (NEt 4 ) 2 [Cu(SC 6 D?h 4 - p -X) 3 ] (X=Cl ( 1 ) and Br ( 2 )), (NEt 4 ) 2 [Ag(SC 6 D?h 4 - p -X) 3 ] (X=Cl ( 3 ) and Br ( 4 )) and novel clusters (NEt 4 ) 2 [M 4 (μ-SC 6 D?h 4 - p -Cl) 6 ] (M=Cu ( 5 ) and Ag( 6 )) D?have been prepared and structurally cD?haracterized by single crystal X-ray diffraction. All tD?he complexes D?have tD?hree-coordinate sites D?having Point-Group D 3D?h symmetry. TD?he tD?hree-coordinate mononuclear silver(I) complexes 3 and 4 are tD?he first examples. TD?he M–S stretcD?hing bands were determined by far-IR and FT-Raman spectroscopies; ν (Cu–S) 363–372 cm −1 and ν (Ag–S) 353–363 cm −1 . TD?hese results indicate tD?hat M–S stretcD?hing vibration energy in tD?he tD?hree-coordinate metal(I) site of tD?he mononuclear compounds or clusters is around 340–380 cm −1 , and it is a useful tool for determining tD?heir coordination modes.
