Reactions of tellurium halides with sulfur N,N'-bis(trimethylsilyl)diimide-preparation of the first fluorotellurium nitride

“…Although a brown solid was obtained from a reaction involving tellurium(IV) fluoride and 1 in 1:4 molar ratio in THF, no information with respect to its identity could be obtained since it was found to explode violently on treatment with a spatula. 22) 8929 (3) 804 (3) 7070 (2) 16(1) N( 23) 10187 (3) 2886 (3) 5425 (3) 18 (1) N( 31) 7610 (3) 2372 (3) 2697 (2) 14(1) N( 33) 9415 (3) 3803 (3) 3191 (2)…”

The 1,2,3,5-ditelluradiazolyl [HCN2Te2] species. Theoretical characterizations of the cation, radical, and radical dimers

“…(16)) can be made. These comparisons are only approximate as the available experimental results are for rather different compounds (15,16). (Spin contamination in the UHF treatment of the radicals might have geometrical consequences.…”

Pyramidal Inversion Isomers in the Solid-State Structure of the Tricyclic Antimony−Tellurium Imido Complex TeSb2Cl2(NtBu)4

“…The identity of the minor product from the reaction of 1 and 2 was determined by X-ray analysis to be Cl 2 Te(μ-N t Bu) 2 Sb[N(H) t Bu] ( 4 ), which involves chelation of the dianionic ligand [ t BuN(H)Sb(N t Bu) 2 ] 2- to a TeCl 2 2+ unit. Related bis-imido complexes of tellurium dichloride are either monomeric [(Ph 3 PN) 2 TeCl 2 and (Ph 2 CN) 2 TeCl 2 ] or dimeric [(Me 3 PN) 2 TeCl 2 ], or they form extended networks through weak Te···Cl interactions [MeN[PhBN(Me)] 2 TeCl 2 , (Ph 2 SN) 2 TeCl 2 , [(Me 3 Si) 2 N] 2 TeCl 2 , and [Cl 2 Te(μ-N t Bu) 2 TeCl 2 ] 10 ]. Complex 4 also forms an extended structure (Figure ), but in this case, the weak intermolecular interactions involve Sb···Cl, rather than Te···Cl, contacts in the range 3.290(3)−3.453(3) Å (cf., sum of van der Waals radii for Sb and Cl = 3.80 Å 17 or 4.0 Å 22 ).…”
