Crystal and molecular structure of the [Y(Phen){( i -C4H9)2PS2}2NO3] mixed-ligand compound

The Y(Phen){(i-C₄H₉)₂PS₂}₂NO₃] mixed-ligand compound (I) was synthesized. Its structure was determined by X-ray diffraction analysis (X8 APEX diffractometer, λMoK _α , 3788 F _hkl , R = 0.0677). Crystals I are orthorhombic: a = 10.6495(8) Å, b = 20.006(2) Å, c = 35.317(4) Å, V = 7524.4(13) ų, Z = 8, ρ_calc = 1.324 g/cm³, space group Pbca. The structure is built of mononuclear discrete molecules. The N₂O₂S₄ coordination polyhedron of the Y atom is a distorted dodecahedron. Original Russian Text Copyright ? 2008 by V. L. Varand, L. A.
