摘要：Reactions between [Nb6Cl12(CN)(6)](4-) and [Mn(salen)](+) in MeOH-H2O solvent mixture led to the formation of a new compound:
   {[(Mn-2(salen)(2))][[Mn(salen)(H2O)](0.67)[Mn(salen)(MeOH)](1.33)(Nb6Cl12(CN)(6))]}center dot 1.7H(2)O center dot 2MeOH (1). Single crystal X-ray analysis has shown that 1 possesses 1D framework built of heterotrimeric supramolecular anions, {[Mn(salen)(s)](2)[Nb6Cl12(CN)(6)]}(2-) and [Mn-2(salen)(2)](2+) phenoxo bridged dimers linked to each other through two cyanide ligands located in axial positions. When 1 was left in a methanolic solution of (Me4N)(+), its 1D framework was transformed into a 2D framework of the previously reported compound [Me4N](2)[(Mn(salen))(2)(Nb6Cl12(CN)(6)))] (2) which has a 2D anionic 4,4-network built of [Nb6Cl12(CN)(6)](4-) and [Mn(salen)](+) nodes linked by CN ligands (Zhou, Day and Lachgar, Chem. Mater., 2004, 16, 4870).(1) Magnetic susceptibility measurements indicate that 1 exhibits weak antiferromagnetic interactions due to the phenolate-bridged out-of-plane Mn(III) dimers with J = -1.50(5) cm-(1). Thermal stability of 1 was studied.
