【 摘 要 】

A one-pot synthesis, that includes CuCl2$cdot$2H2O, Na2mnt, H2salph and Mn(CH3COO)3$cdot$H2O, leads to the isolation of a trinuclear heterometallic compound [{MnIII(salph)(H2O)}2{CuII(mnt)2}]$cdot$4DMF (1) formed by Mn$cdots$S-Cu-S$cdots$Mn supramolecular interactions. Compound 1 crystallizes in the monoclinic space group 𝑃21/𝑐 with 𝑎 = 13.433(4), 𝑏 = 16.283(5), 𝑐 = 15.072(4) Å, 𝛽 = 107.785(4)°, 𝑍 = 2. In the crystal structure, the complex anion [CuII(mnt)2]2- bridges two [MnIII(salph)(H2O)]1+ cations through Mn$cdots$S contacts. The non-covalent hydrogen bonding and 𝜋-𝜋 interactions among the trinuclear [{MnIII(salph)(H2O)}2{CuII(mnt)2}] complexes lead to an extended chain-like arrangement of [MnIII(salph) (H2O)]1+ cations with [CuII(mnt)2]2- anions embedded in between these chains.
