Sažetak
The synthesis and crystal and molecular structure of the
bis(trifluoroacetato)(trimesitylphospine)mercuryiII) dimer are reported.
Crystals are triclinic, space group Pl with one centrosymmetric
dimer in a unit cell of dimensions a = 12.854(3), b =
= 12.877(4), c = 12.405(2) A, a = 107.34(2), (J = 118.55(2), y = 63.65
(2) 0
• The structure was solved by the heavy atom method and
refined by full-matrix least-squares calculation, R = 0.051 for
1656 observed reflections measured by diffractometer. The mercury
coord!nation is characterized by three strong nearly coplanar
bonds (Hg-P 2.415(5), Hg-0(12) 2.29(2), Hg-0 2.18(2) A) and two
weaker bonds (Hg-0(22) 2.95(2) and Hg-0(11)' 2.66(2) A). The Pmes3
ligand has a regular propeller conformation (Hg-P-C-C torsion
angles 45-49 °), enlarged C-P-C angles (mean 112.6(9) 0
), decreased Hg-P-C angles (mean 106.2(6) 0
), and a maximum cone angle of 208 °. Bridging in the solid state utilizes both oxygens of the CFsC02 moiety; the complex becomes monomeric in dichloroethane solution. Infrared, 1H, and 31P NMR data are discussed.
