A novel coordination polymer of [Co( p-CPOA)(2,2′-bipy)(H2O)]n ( p-CPOA2-=4-carboxylphenoxyacetate dianion, 2,2′-bipy=2,2′-bipyridine) was synthesized and characterized by elemental analysis, IR and X-ray single cr...A novel coordination polymer of [Co( p-CPOA)(2,2′-bipy)(H2O)]n ( p-CPOA2-=4-carboxylphenoxyacetate dianion, 2,2′-bipy=2,2′-bipyridine) was synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction. The title complex crystallizes in monoclinic space group C2/c, with a=1.424 4(3) nm, b=1.316 6(3) nm, c=1.947 7(4) nm, β=104.56(3)°. V=3.535 3(14) nm3, Z=8, R=0.028 5, wR=0.089 1. The cobalt(Ⅱ) ion displays a distorted octahedral coordination geometry, defined by three carboxyl oxygen atoms from different p-CPOA2- groups, two nitrogen atoms from 2,2′-bipyridine ligand and one water molecule. The cobalt atoms are bridged by p-CPOA2- groups, forming a one-dimensional chain structure along a axis. The adjacent Co...Co atoms distance is 0.996 8 nm. A layer supramolecular network is contrsucted by the hydrogen bonds and π-π stacking interactions. CCDC: 220039.展开更多
Co(NO3)2, N carbazolyacetic acid and 4,4′ bipyridyl can give rise to a novel coordination polymer [Co2(Cabo)2(NO3)2(4,4′ bipy)2]n using a fritted U tube.

Single crystal X ray diffraction displays in the complex, each Co? is six coordinated by two N atoms from different 4,4′ bipyridyl ligands, two O atoms of the bridge from two N carbazolyacetic acid and two O atoms of one nitrate anion to form a distorted octahedral. Two O atoms of the carboxyl group act as bridge to link two Co? atoms. The resulting structure is a ladder polymer. CCDC: 211713.展开更多

The crystal belongs to the monoclinic system and space group is P2/n with a=1.040 6(3) nm, b=1.138 8(4) nm, c=1.854 7(6) nm, β=102.991(6)°, V= 2.141 6(12) nm 3, Z=2, D c=1.443 Mg/m 3, M r=930.62, μ=0.842 mm -1, F(000)=952, GOF= 1.072, R=0.065 4, wR=0.146 8[I>2σ(I)]. There are two crystallographically independent Co(Ⅱ) ions in the title complex. The Hisor 2- and 4,4′-bpy link the metal ions into 2D grids with dimension of 0.522 3 nm×1.138 8 nm. There are O—H…O and N—H…O hydrogen bonds in the complex resulting in the formation of 3D network with 1D channels, in which are free 4,4′-bpy molecules.展开更多
