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.
