Addition of two equivalents of NaS2CNHBz to CuSO4 affords the yellow diamagnetic coordination polymer [Cu(S2CNHBz)]n (1), resulting from intramolecular electron-transfer and concomitant formation of the thiourea, (BzNH)2C＝S. 1 reacts with PPh3 and 1,1′-bis(diphenylphosphino)ferrocene (dppf) in CH2Cl2 to give monomeric [Cu(κ2-S2CNHBz)(PPh3)2] (2) and [Cu(κ2-S2CNHBz)(κ2-dppf)] (3), respectively, both of which have been crystallographically characterised. While 1 is thermally stable in dimethylsulfoxide (DMSO) up to ca. 70 °C, addition of nBuNH2 to 1 leads to its rapid decomposition to afford CuS (covellite) nanomaterials; indeed in neat nBuNH2, covellite formation is rapid at room temperature. Thus, 1 serves as an effective low-temperature base-induced single source precursor to covellite nanomaterials. [ABSTRACT FROM AUTHOR] |
