Synthesis and Crystal Structure of Pd(ptac-C,N)(acac-O,O) |

| Abstract: | A stable organometallic Pd (Ⅱ) compound Pd(ptac-C,N)(acac-O,O) (Hacac = acetyl acetone, Hptac = 3-(2-pyridinethioxy)-acac, formula: C15H17NO4SPd, Mr = 413.76) 1 has been synthesized and its crystal structure was determined by X-ray crystallography. The crystal is of monoclinic with space group C2/c, a = 17.9342(3), b = 17.7791(4), c = 13.1800(1) A。, a = 128.400(1)b, V = 3293.5(1) A。3, Z = 8, Dc = 1.669 g/cm3, F(000) = 1664, u= 1.269 mm-1, R = 0.0261 and wR = 0.0710 for 2653 observed reflections (I > 2(I). There exist two Pd rings in the title compound, C(14)-O(4)-Pd-O(3)-C(12)-C(13) and C(1)-N-Pd-C(8)-S, with the palladium atom taking a square-planar coordination. Two oxygen atoms from the acetyl acetone ligand (Pd-O, 1.991(2) and 2.036(2uA。), one N atom (Pd-N 2.019 A。) and the r-carbon atom (Pd-C 2.067(3) A。) from the ptac ligand are coordinated to Pd. |
