| Abstract: | Syntheses and Structure Elucidations of Novel (Ironcarbonyl)zinc and ‐cadmium Chloride Derivatives Reactions of zinc/cadmium chloride with Na2Fe(CO)4] lead to a number of new (iron carbonyl)zinc/cadmium chlorides, wherein the reaction course depends on the used solvent used. In the reaction of ZnCl2 with Na2Fe(CO)4], three new substances can be prepared. The compound Zn2Cl2Fe(CO)4(THF)2] ( 1 ), which consists of neutral polymeres, is formed in THF, the ionic compound Na(DME)3]Zn2Cl3Fe(CO)4] ( 2 ) forms in DME, and from a mixture of THF and TMEDA the compound Zn2Cl2Fe(CO)4(TMEDA)2] ( 3 ) is obtained as a monomere. Also by using CdCl2, the reaction with Na2Fe(CO)4] in THF leads to the polymeric compound ((Cd4Cl6)Fe(CO)4(THF)5] ( 4 )). Carrying out the reaction in a mixture of toluene and DME leads to the formation of the ionic compound Na(DME)3]2Cd6{Fe(CO)4}6Cl2(DME)2] ( 5 ) in which an annular dianion consisting of twelve metal atoms is found. From an aqueous solution and subsequent work‐up in THF, the compound Fe(THF)4(H2O)2]Cd8{Fe(CO)4}4Cl9(THF)6]2 ( 6 ) can be prepared which contains an cluster anion that is built of anellated six membered rings. |
