Synthesis And Crystal Structures Of Hydrogen Bonded Inclusion Compounds Built With Guanylthiourea

Herein we report 6 novel crystal structures.In these compounds,with the existence of the ancillary molecules such as tartaric acid,fumaric acid and maleic acid,the host planar molecule of guanylthiourea is selected to interact with the guest templates of alkylammonium ions to generate various crystal structures.All the compounds were determined by single X-ray diffraction analysis.Guanylthiourea is a planar hydrogen bond reagent that can be regarded as the combination of triangle amidine and thiourea.Herein 6 inclusion compounds were prepared with guanylthiourea and different auxiliary molecules with the existence of alkylammonium guest templates.Among these compounds,2.1,2.3,2.4 and 2.6 are sandwich-like structures,and 2.2 and 2.5 did not form sandwich-like structures due to the absence of alkylammonium guest templates.By studying these crystal structures,it is helpful to further understand the hydrogen bonding and other weak molecular interactions.Obviously,it provides the related references to design crystal structure and directs us to synthesize other novel hydrogen-bond inclusion compounds with different properties.
