Abstract The crystal structure of TeCl2(C7H7O)(C7H11O2) has been determined from three dimensional, single crystal X-ray diffraction data. It crystallizes in the monoclinic space group C2/c with the lattice constantsa=24.551(5),b=11.435(2),c=12.368(2)Å,β=97.33(1)° andZ=8,D X=1.67 g cm−3. Final least-squares refinement based on 3023 independent observed reflections yieldedR=0.026. The Teiv ion is in a trigonal bipyramidal configuration with its lone pair of electrons at one of the equatorial positions. Distances and angles are: Te-Cl=2.495(1), 2.517(1); Te-C=2.134(3), 2.106(3)(aryl)Å; Cl-Te-Cl=173.45(4), Cl-Te-C=88.11(9), 88.60(9), 88.72(9), 86.06(9); C-Te-C=96.5(1)°. There are two secondary bonds to the tellurium: Te⋯Cl=3.824(1) and Te⋯O(2)=3.006(1)Å. The methyl groupα to the carbonyl oxygen and the aryltelluro moiety exhibit atrans 2,4 relationship.
