Six hydrous Cd(II) coordination polymers based on a scorpion-like 5-(3-pyridylmethoxy)isophthalic acid (H 2 L), namely {[CdL(H 2 O)]·2H 2 O} n ( 1 ), [Cd 4 L 4 (H 2 O) 4 ] n ( 2 ), [CdL(H 2 O)] n ( 3 ), [CdL(H 2 O) 2 ] n ( 4 ), {[CdL(H 2 O)]·H 2 O} n ( 5 ) and [CdL] n ( 6 ), were hydrothermally synthesized and characterized by EA, IR, PXRD, TG-DSC and X-ray structural analysis. Temperature and solvent play crucial roles in the preparation of the coordination polymers. Complexes 1 – 3 were prepared in a H 2 O-DMF (6:2) solvent system at slightly different temperature (85, 100 and 120 °C). Complexes 4 – 6 were prepared in different H 2 O-DMF solvents (6:3 and 8:2) and H 2 O-MeCN (3:6) solvent. These complexes possess different coordinated and/or lattice water molecules, and exhibit structural diversity and various topology nets. Complex 1 is a 2D double-layered coordination polymer. Complex 2 features a 3D porous framework with irl topology. Complex 3 displays a 2D double-layered network. Complex 4 is a 3D coordination polymer with sra topology. Complex 5 exhibits a 3D wave-like framework with sra topology. Complex 6 is a 3D coordination polymer with self-catenated hxg-d topology. 5-(3-Pyridylmethoxy)isophthalate adopts three types of coordination modes. These complexes exhibit higher thermal stability and emit strong luminescence. [ABSTRACT FROM AUTHOR]

Six coordination polymers based on 5-(3-pyridylmethoxy)isophthalic acid (H 2 L), namely [Zn 2 L 2 ] n ( 1 ), [Zn 2 L 2 (1,3-bix)] n ( 2 ), [CdL(1,3-bix)] n ·2 n H 2 O ( 3 ), [CdL(azpy) 0.5 (H 2 O)] n ( 4 ), [CdL(btx) 0.5 ] n ( 5 ), and [CdL(btmb)] n ·2 n H 2 O ( 6 ) (1,3-bix = 1,3-bis(imidazol-1-ylmethyl)benzene, azpy = 4,4′-azobispyridine, btx = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene, btmb = 4,4′-bis(1,2,4-triazol-1-ylmethyl)biphenyl), have been synthesized and characterized by elemental analyses, IR spectra, PXRD, thermogravimetry and X-ray structural analysis. Complex 1 is a 3D coordination polymer, simplified as a 4-nodal (4,4,5,5)-connected topology net with point symbol {4 3 .6 3 }{4 3 .6 2 .8}{4 4 .6 5 .8}{4 4 .6 4 .8 2 }. Complex 2 is a 3D coordination polymer, simplified as a crs - d topology net with point symbol {6;8 2 }{6 2 ;8 3 ;10}. Complex 3 is a 2D coordination polymer with a 2-nodal (3,5)-connected topology net. Complex 4 exhibits a 2D double-layered network with a 2-nodal (3,4)-connected topology net, assembled by two parallel [CdL] n layers pillared by azpy spacer. Complex 5 is a 3D coordination polymer, simplified as a 2-nodal (3,8)-connected topology net with point symbol {4 3 } 2 {4 6 .6 18 .8 4 }. Complex 6 shows a 2D double-layered network with a 2-nodal (3,5)-connected topology net, constructed from wave-like [CdL] n network pillared by btmb spacer. 5-(3-Pyridylmethoxy)isophthalate exhibits five types of coordination modes. Anhydrous or dehydrated substances of 1 – 6 were thermally stable to 300–400 °C. These Zn(II)/Cd(II) complexes emit blue luminescence originating from ligand-centered emission.
