Description:
Four novel In3+ and Cd2+ based 1D coordination compounds constructed by double betaine ligands were synthesized and characterized structurally and optically. They assemble into 3D supra-molecular architectures via different stacking or entanglement of 1D zigzag shaped chains, in which C-H…Cl and C-H…O hydrogen bonding interactions play a dramatic impact. Compound 1 displays a 1D + 1D 3D 4-connect lvt net with 42*84 topology. Compound 2 assembles into a 3D architecture by inclined stacking of the adjacent zigzag chains. Compound 3 displays a 2D + 2D 3D inclined polycatenation based on the resulting 2D (6, 3) layers that constructed by 1D chains. Compound 4 displays a 3D supra-molecular architecture based on 1D chains, which were connected via the hydrogen bonding. Meanwhile, four compounds emit in the range of visible region owing to the intra-ligand π* π and/or π* n electron transition induced florescence.
