The novel complex {[Co(bipy)(azpy)2(NCS)2]· H2O}n (where bipy=4,4′ bipyridine, azpy=4,4′ azobisp yridine) has been synthesized and characterized by elemental analyses, IR, UV, thermal analyses, and variable tem...The novel complex {[Co(bipy)(azpy)2(NCS)2]· H2O}n (where bipy=4,4′ bipyridine, azpy=4,4′ azobisp yridine) has been synthesized and characterized by elemental analyses, IR, UV, thermal analyses, and variable temperature magnetic susceptibility. The crystal (C32H26CoN12OS2, Mr=717.70) belongs to the orthorhombic, space group Pnna, a=2.21312(16)nm, b=1.40403(10)nm, c=1.14237(8)nm, V=3.5497(4)nm3, Z=4, Dc=1.343g· cm- 3, μ =0.645mm- 1, F(000)=1476, and final R1=0.0691, wR2=0.1129 for 231 parameters and 1674 observed reflections [I >2.00σ (I)]. The Co(Ⅱ) atom is, in a distorted octahedral geometry, coordinated by six nitrogen atoms from two bridging bipy, two monodentate azpy, and two thiocyanate groups. The bridging ligand bipy links Co(Ⅱ) atoms to form the infinite “ rod" with terminal coordination azpy ligand acting as sidearms. Unprecedented three parallel interpenetrating two dimensional (4,4) networks and novel infinite triple helices are formed via hydrogen bonding interactions. CCDC: 155588.展开更多
A novel coordination ploymer [Cd(HO-BDC)(phen)·H2O]n (where HO-BDC is 5-Hydroxyisophthalic acid and phen is 1,10-phenanthroline) has been synthesized and characterized by elemental analysis, IR spectra and single...A novel coordination ploymer [Cd(HO-BDC)(phen)·H2O]n (where HO-BDC is 5-Hydroxyisophthalic acid and phen is 1,10-phenanthroline) has been synthesized and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2/c, with a=0.876 4(2) nm, b=1.233 0(3) nm, c=1.761 2(4) nm, β=109.152(9)°, V=1.797 8(7) nm3, Z=4, Mr=490.73, Dc=1.813 g·cm-3, F(000)=976, μ=1.258 mm-1, the final R=0.043 8 and wR=0.098 9 for 2 880 observed reflections with I>2σ(I). The structural analysis shows that the complex has a one-dimensional chain structure. CCDC: 609770.展开更多
