Catena-[bis (3-methyl-4-nitropyridine N-oxide ) cadmiumdichloride],[Cd(C_6H_6N_2O_3)_2Cl_2], M_r= 491. 56, monoclinic , P2_1, a= 3. 799 (3), b= 29. 231 ( 9),c=7. 679(5) A, β=100. 19(6)°, V=839. 4 A ̄3, Z=2, D_c= 1. 94 g/cm ̄3, λ(MoKa)= 0. 71069 A, F(000) =484, P(MoKa) = 16. 5 cm ̄(-1), final R=0. 038 for 1202 Observed reflections, T= 296K. The Cd atom is octahedrally coordinated by two O atoms from the trans 3-methyl-4-nitropyridine N-oxide (pom) ligands in the axial positions and four Cl atoms lying in the equatorial plane. The coordination octahedra form chains along the short a axis by edge sharing through the Cl atoms. 展开更多
