One-pot synthesis of an Mn(III)–Cu(II)–Mn(III) trinuclear heterometallic compound formed by Mn"S–Cu–S"Mn supramolecular interactions: Crystal structure of [{MnIII(salph)(H2O)}2{CuII(mnt)2}]×4DMF

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)}2{CuII(mnt)2}]4DMF (1) formed by Mn"S–Cu–S"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, =beta107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 pi–pi 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.
