Synthesis and structure of a novel infinite triple helices coordination polymer {[Mn(bipy)(azpy)2(NCS)2]·H2O}n(bipy=4,4′-bipyridine, azpy = 4,4′-azobispyridine)

A novel complex {[Mn(bipy)(azpy)2(NCS)2]·H2O}n (where bipy =4,4′-bipyridine, azpy = 4,4′-azobispyridine) is synthesized and characterized. The molecule structure shows that it is composed of an infinite “rod” with open sidearms. Two-dimensional undulating plane networks with large rhombic channels ca. 21.7×11.6 Å is constructed by the neutral rod via hydrogen-bonding interaction. Three parallel interpenetrating two-dimensional (4,4) networks form a novel infinite triple helices with rhombic channels ca. 19×9 Å.
