| Abstract: | The self‐assembly of 4 ‐ MTPP 4 ‐ MTPP = 2‐(methylthio)‐4‐(pyridin‐4‐yl)pyrimidine] with Cu(NO3)2 and AgNO3 was structurally investigated. For Cu(NO3)2, a discrete mononuclear CuII coordination compound, Cu( 4 ‐ MTPP )2(NO3)2] ( 1 ), resulted that is exclusively based on Cu–N coordination. For AgNO3, a unique one‐dimensional double‐chain structure ( 2 ) was obtained with the Ag–N distances varying from 2.181(9) to 2.223(9) Å, and the average Ag–S distance being 2.98 Å. Compared to zero‐dimensional 1 , the extension to one‐dimensional 2 is considered to result from the specific affinity between Ag+ and the ligand 4 ‐ MTPP that is attributed to the strong coordinating tendency of silver for aromatic nitrogen and thioether sulfur atoms. |
