Abstract

A one-pot synthesis, that includes CuCl2.2H2O, Na2mnt, H2salph and Mn(CH3COO)3.H2O, leads to the isolation of a trinuclear heterometallic compound [MnIII(salph)(H2O)2CuII(mnt)2].4DMF (1) formed by Mn…S-Cu-S…Mn supramolecular interactions. Compound1 crystallizes in the monoclinic space groupP21/c witha = 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…S contacts. The non-covalent hydrogen bonding and π-π interactions among the trinuclear [MnIII (salph)(H2O)2CuII(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.
