Synthesis, Infrared and X-Ray Studies of Diphenyltellurium(IV) Nitrosocarbamylcyanmethanides. X-Ray Evidence for Stability of a Tritelluroxane Fragment -Ph2Te-O-Ph2Te-O-Ph2Te-

Abstract: Tellurium(IV), Oximes, X-Ray Diphenyltellurium(IV) derivatives of the types Ph2Te{ACO}2 (1), Ph4Te2 0 {AC0}2 (2) and PhöTe.^C^ACO^ (3) (ACO = nitrosocarbamylcyanmethanide _ 0 NC(CN)C(0 )NH2) have been prepared. The IR spectroscopic data reveal that the ambidentate ligands are coordinated to the tellurium(IV) atom in a monodentate manner via the nitroso oxygen atom. The crystal and molecular structure of 3 has been determined from X-ray diffraction data (triclinic, space group Pi with a = 12.382 (2)

“…All six cyanoxime anions in complex 4 are planar and demonstrate the cis-anti configuration contrary to that found in MH(ACO) 2 (M ¼ Na þ , K þ ) [55,56], M 0 (ACO) (M 0 ¼ Rb þ , Cs þ ) [57], and several tellurium [69], antimony [16,19,70], and tin [26,71,72] compounds. In the latter three groups of compounds, the ACO À ligands are bound to the Te(IV), Sb(IV) and Sn(IV) central atoms in a monodentate fashion via the oxygen of the oxime group.…”

“…In the tetranuclear [Mn 4 O 2 (ccnm) 4 (MeCN) 2 (H 2 O) 6 ] 2+ complex cation, only the nitroso O atom is coordinated as a bridge; thus the ccnm ligand is tridentate (Price et al, 2003). Ccnm can also coordinate in a monodentate manner, either in the oxime form, when it is coordinated via the oxime O atom in a trans-anti configuration to transition metals, such as Sn IV (Gerasimchuk et al, 2007), Sb V (Domasevitch et al, 2000) and Te IV (Domasevitch et al, 1996), or in the nitrile form, when it is coordinated via the nitrile N atom, as in the [Cu(ccnm) 4 ] 2À complex anion, in which two ccnm ligands are coordinated via the nitrile N atoms, while the other two are coordinated in a chelating manner in the nitroso form (Chesman et al, 2010). Finally, ccnm exists as a free anion balanced by simple or complex cations (Domashevskaya et al, 1989;Gerasimchuk et al, 2010;Izgorodina et al, 2010;Janikowski et al, 2013;Fonari et al, 2005).…”

“…1.44(1)-1.45(1) A, Table IV] and in each case are slightly less than the similar parameters in the 2-pyridyl-, 2-quinolyl and carbamoyloximes. Thus, the C(NO)-CONHo bond lengths in isonitrosocyanoacetamide HONC(CN)CONH2 [H(X)] were found to be 1.494 (7) A for H(X)*(18-crown-6)*H.O [23]; 1.47(1), 1.474(9) A for Ph6Te30 2{X}2 [24] and the appropriate parameters for isonitrosomalonodiamide in the copper(II) complex [9] are 1.469(2) and 1.486(2) A.…”
