Abstract. M r= , triclinic, P1, a = 9.008 (2), b=17.194(4), c= 14. 501(2) /~,, ct=128.34(2), fl =95.60(2), y=97.13(2) ° , V=1703.44/~3, Z=2, D x= 1.654Mgm -3, MoKet, 2=0.71069./k, p= 1.295 mm -~, F(000) = 864, T = 293 K, R = 0.042 and R w = 0.045 for 3482 unique observed reflections. In the molecule, the central tellurium atom is bonded to all eight sulphur atoms in a highly distorted dodecahedral configuration. The two planar trapezoids, each containing a TeS4 group, make an angle of 86.50 (1) ° with each other. The Te-S bond lengths are in the range 2.637 (4)-2.857 (4) A, the average being 2.738 (4) A. The extensive hydrogen bonding of the terminal hydroxyl groups in the range 2.678 (13)-2.763 (14) ,~ hinders the auto redox reaction in TeL 4 and also provides stability for the crystal packing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
