摘要
The complex Zn(Mept) 2 (Mept=Bis(3-methyl-oxopyridine-2-thionato)) was obtained by the reaction of MeHpt with ZnSO 4 in ethanol. A single crystal X-ray study shows that the complex bis(3-Me-oxopyridine-2-thionato)zinc(II) (Zn 2C 24 H 24 N 4O 4S 4) is a dimer. The oxygen and sulfur atoms from Mept ligand coordinates to a zinc atom forming (3-Me-oxopyridine-2-thionato)zinc(II) monomer, and every two monomeric units are linked centrosymmetrically by two oxygen bridges. The compound Zn(Mept) 2 belongs to the monoclinic system with space group P2 1/c, a=7.7627(9), b = 10.3335(7), c=17.4528(13) , β=99.134(9)°, V=1382.2(2) 3, Z=2, M r=691.46, D c=1.661 g/cm 3, μ=2.076 mm -1 , F(000)=704, R=0\^0463, R w=0.0747 for 3378 reflections with I>2σ(I). The coordination geometry about each Zn(II) ion is a distorted trigonal bipyramid. The Zn atom is coordinated by two sulfur atoms (Zn(1)-S(1) 2.307(1); Zn(1)-S(2) 2.295(2)) and one oxygen atom (Zn-O(2A) 2.126(3)) in the equatorial plane, while the two oxygen atoms of Mept ligands (Zn(1)-O(1) 2\^050(3), Zn(1)-O(2) 2\^172(3)) occupy the axial positions with O(1)-Zn(1)-O(2) 177\^2(1)°.
