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

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.
