| Abstract: The mixed metal complex MoS4Cu2(NC5H5)4(NC5H5=pyridine)is crystalized in the triclinic space group P1.There are two molecules per unit cell with the crystal parameters: a=9.465(5), b=9.463(4), c=14.053(3)Å,α=95.16(3),β=84.89(3), r=95.91(4)°. V=1243(2)Å3, Mr=667.7, Dc=1.784g·cm-3, the final R=0.039 and Rω=0.045. The linear chain trinuclear skeleton of the MoS4Cu2 moiety has quite good D2d symmetry, in which the two Mo-Cu distances are 2.638, 2.663Å respectivcly.Thc d-π* back bonding(by EHMO method)between the terminal ligands pyridine and the metal atoms Cu makes the Mo-Cu interaction stronger to a certain extent. |
