| 摘 要： | 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 vari-able-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, coordi-nated 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. |

| Abstract: | 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 vari-able-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 parametersand 1674 observed reflections I ＞ 2.00 σ(I) ]. The Co (Ⅱ) atom is, in a distorted octahedral geometry, coordi-nated by six nitrogen atoms from two bridging bipy, two monodentate azpy, and two thiocyanate groups. Thebridging ligand bipy links Co (Ⅱ) atoms to form the infinite "rod" with terminal coordination azpy ligand acting assidearms. Unprecedented three parallel interpenetrating two-dimensional (4, 4) networks and novel infinite triplehelices are formed via hydrogen-bonding interactions. CCDC: 155588. |
