The amino-functionalised xanthate NaS2COC2H4 N(Me)C2H4NMe2 (1) was synthesised, and its structure was determined to be a coordination polymer incorporating a six-coordinate metal with S3N2O ligation and in which the ligand delivers κ2-S,S chelate, κ2-S,O chelate, κ2-N,N chelate, and μ2-S bridging modes. 1 has been used to prepare the copper complex (Ph3P)2CuS2COC2H4N(Me)C2H4NMe2 (5), although reactions with various Zn(II) and Cd(II) salts yielded only the metal sulphide decomposition product and the free acid as its 1,1,4-trimethylpiperazinium salt (2). Attempts to insert CS2 into the alkoxides RMOC2H4N(Me)C2H4NMe2 (M=Zn, R=Et [3]; M=Cd, R=Me [4]) also failed to give the desired group 12 derivative of the amino-functionalised xanthate. The structures of 2–5 are also reported.
