Abstract
A double complex salt [Co(N2C2H8)3][AuBr4]2Br is obtained and characterized using single crystal X-ray diffraction analysis. The crystallographic data of C6H24Au2Br9CoN6 are as follows: a = 21.6479(17) Å, b = 14.9085(12) Å, c = 8.2676(7) Å, β = 110.820(2)°, V = 1538.92(12) Å3, C2/c space group, Z = 4, dx = 3.602 g/cm3. Square planar coordination of the gold atom in the complex anion is completed to a tetragonal pyramid by an additional bromine atom of the adjacent complex anion at the Au…Br distance of 3.677 Å.
