Publikováno v: Journal of Structural Chemistry. 49:175-180
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) A, b = 20.
