| Abstract |
The new heterometallic 2D polymer [Cu(en)(2)Cd(dca)(2)(SCN)(2)]n (en = ethylenediamine; dca = dicyanamide, N(CN)(2)(-)), the first example of a compound containing the unique mixed-anion Cd(dca)2(SCN, fragment, has been prepared from copper powder, cadmium dicyanamide, ammonium thiocyanate and ethylenediamine in methanol solution in air. The polymeric sheets of the compound comprise two different rings - 28-membered [CU2Cd4( mu(1,5)-dca)(2)( mu(1,3)-NCS)(4)] macrocycles in which two 12-membered [Cd-2(mu(1.5)-dca)(2)] rings form sections.
