Synthesis and single crystal structural investigations on quaternary salts of tellurated alkylamine derivatives

Crystal structure ofrac-(3aR*,9aS*)-4,4,4-trichloro-1,2,3,3a,4,9a-hexahydro-4λ5,9λ4-cyclopenta[4,5][1,3]tellurazolo[3,2-a]pyridine

“…The bond lengths from the tellurium atom to the two chlorine atoms arranged trans to each other [2.5009 (7)/2.5145 7and 2.5184 (7)/2.5220 (8) Å for the two crystallographically independent molecules, respectively] are close to those in related complexes (Singh et al, 1990;Sundberg et al, 1994;Zukerman-Schpector et al, 2000;Kandasamy et al, 2003;Raghavendra et al, 2006;Dutton et al, 2009;Lee et al, 2010;Rakesh et al, 2012). The third Te-Cl distance (2.8786 (7) and 2.8763 (7) Å for the two crystallographically independent molecules, respectively) is substantially longer than the other two Te-Cl distances.…”
