zinc,4,4'-bipyridine,coordination polymer,helical structures
The crystal of the title compound (C10H18N2O9SZn Mr= 407. 69) belongs to the hexagonal system, space group P65 with cell parameters: a= 11. 411(2), c=20. 908(4) A, V=2357.7(7)A 3, Z=6, Dc=1. 723g/cm3, F(000)=1260,μ(MoKα) =1. 743mm-1. The final R and wR factors are 0. 072 and 0. 178 respectively for 1335 observed reflections. In the structure, zinc ions are bridged by 4,4'-bipyridine to form infinite chains. The sheets containing parallel chains stack along a 65 screw axis to give a helical staircase motif. The helical structure is mainly controlled by the hydrogen bonds.
