Solvent-controlled assembly of supramolecular isomers: 2D (4,4) network, 1D ribbons of ring, and both 2D (4,4) networks and 1D ribbons of rings polycatenated in a 3D array

Abstract

The reaction of Mn(NCS)2 with the flexible ligand 1,4-bis(1,2,4-triazol-1-yl)butane (btb) in different solvent systems affords three “pseudo” supramolecular isomers 2D (4,4) network [Mn(btb)2(NCS)2](CH2Cl2) (1), 1D ribbons of rings [Mn(btb)2(NCS)2](CH3NO2)2 (2), and [2D-Mn(btb)2(NCS)2][1D-Mn(btb)2(NCS)2] (3) which shows 2D (4,4) networks and 1D ribbons of rings polycatenated in a 3D array.
