Description:
Two coordination polymers based on 1,6-bis(2-methyl-imidazole-1-yl)-hexane (bimh), namely {[Zn 3 (BTC) 2 (bimh)] · (bimh)} n ( 1 ) and {[Zn(IPA)(bimh)] · (CH 3 CH 2 OH) 0.5 } n ( 2 ) (H 3 BTC = trimesic acid, H 2 IPA = isophthalic acid), were synthesized through hydrothermal reactions. In compound 1 , the zinc(II) ions are bridged by BTC 3– ligands to form an undulating infinite two-dimensional (2D) polymeric network. The 3D networks of 1 show a twofold interpenetrating net. In compound 2 , zinc(II) ions are bridged by IPA 2– ligands to form one-dimensional (1D) helical structures. The 2D structures of 2 are further assembled into 3D networks through aromatic π–π stacking interactions. Both compounds exhibit strong photoluminescence at room temperature and may be good candidates for potential luminescence materials.
