| Abstract: | Five copper coordination complexes 1–5 with 2-bppm (2-bppm?=?bis(4-(pyridin-2-yl)pyrimidin-2-ylthio)methane) have been prepared and structurally elucidated. Complexes 1 and 2 are both discrete dinuclear 2?+?2] macrocyclic structures, simultaneously formed in one-pot reaction with Cu(NO3)2 with in situ reduction of Cu2+. Similarly, dinuclear 2?+?2] macrocyclic motifs are found with 3 and 4, which are also obtained by one-pot reaction but with CuCl accompanied by in situ air oxidation of Cu+. Compound 5 exhibits a 1-D chain structure with 2-bppm and Cu2I2 connected one by one. Luminescence is measured for 2, 4, and 5, all based on d10-closed shell Cu(I). |
