| Abstract: | The reaction of ZnSiF6·6H2O with 4,4′-dipyridyldisulfide (4-PDS) in CH3OH afforded the complex Zn(4-PDS)2(SiF6)·3CH3OH]
n
, 1, while the reaction of Zn(ClO4)2·6H2O with l,2-bis(4-pyridyl)ethane (bpa) in CH3OH gave the complex Zn(bpa)2(ClO4)2·CH3OH]
n
, 2. The 4-DPS ligand in 1 is coordinated to the metal centers through both nitrogen atoms to form a 3-D open channel and the distorted octahedral coordination geometry at each zinc center is completed by a pair of trans-F-bonded hexafluorosilicate molecule. Compound 2, the channel-type 1-D chains are interlinked through C–H···O interaction to form 3-D structure with large cavities that are occupied by the methanol molecules. |
