The X‐ray crystal structure of [(dtma)ZnImZn(dtma)]C1O 4 ·2.5H 2 O (Hdtma=4‐Diethyl‐enetriamineacetic acid) was determined. The crystal is of orthorhombic, space group Pbcn with a =14.104(5), b =14.897(5), c =25.384(9)Å, and Z =8. The least‐square refinement of the structure leads to conventional R factor of 0.066. The magnetic properties of [(dtma)CuImZn(dtma)]CIO 4 ·2.5H 2 O were investigated. From the single crystal ESR spectra of Zn—Im—Zn dimer doped with Cu—Im—Zn complex, the anisotropic g and A tensors and electronic spin‐density of the Cu—Zn complex are obtained and the bonding nature of Cu is discussed.
