The reaction of anhydrous zinc chloride with 2,3-thiophenedicarbaldehyde bis(semicarbazone) or 2,3-bis(thiosemicarbazone) leads to the formation of compound {[C6H5N2S]+[ZnCl3(C6H4N2S)]-}, where C6H4N2S is thieno[2,3-d]pyridazine, via an elimination-cyclisation reaction of the semicarbazone or the thiosemicarbazone moiety. Crystal structures of thieno[2,3-d]pyridazine and {[C6H5N2S]+[ZnCl3(C6H4N2S)]-} are described. 2015 Institute of Chemistry, Slovak Academy of Sciences
