TLDR
In this article, the synthesis, properties, and structural characterization of the title compound, C14H10O2S2Te, were reported and solved by the heavy-atom method and refined by full-matrix least squares toR=0.029 andR = 0.027 for 772 diffractometer data.Abstract:
The synthesis, properties, and structural characterization of the title compound, C14H10O2S2Te, are reported. The crystals are monoclinic, space groupC2/c (No. 15) witha=24.369(6),b=4.333(2),c=14.569(3) A, andβ=109.56(2)°,V=1449.57 A3,M=402, andD
x
=1.843 g cm−3 forZ=4. The structure was solved by the heavy-atom method and refined by full-matrix least squares toR=0.029 andR
w
=0.027 for 772 diffractometer data. Crystal structure analysis and IR spectroscopic study indicate that the tellurium is covalently bonded to sulfur. There are weak secondary interactions between tellurium and oxygen which complete an S2O2 coordination around tellurium.read more

TL;DR: Natural bond orbital analyses of dithio-compounds revealed that two types of orbital interactions play a role in the bonding of E[S(2)S(1)CC(6)H(4)OMe-2](2) (E = Se, Te) and the former play a particularly predominant role.

X-ray scattering factors computed from numerical Hartree–Fock wave functions
D. T. Cromer,J. B. Mann +1 more
TL;DR: In this paper, the Hartree-Fock wave function was used to compute X-ray scattering factors for neutral atoms from He to Lw and for most of the chemically significant ions through Lu3+ through Lu 3+.

Relativistic Calculation of Anomalous Scattering Factors for X Rays
Don T. Cromer,David A. Liberman +1 more
TL;DR: In this paper, relativistic calculations of the photoelectric cross section have been made and the integral for the principal contribution to Δf′ has been evaluated numerically without approximation to the form of the cross section-vs-energy curve, as has been done in previous calculations.

Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule
TL;DR: In this paper, the x-ray form factors for a bonded hydrogen in the hydrogen molecule have been calculated for a spherical approximation to the bonded atom, and the corresponding complex scattering factors have also been calculated.

Secondary Bonding to Nonmetallic Elements
TL;DR: In this article, a qualitative explanation of the secondary bond behavior is given, and it is argued that the secondary bonds are the result of directed forces rather than electrostatic or non-nondirectional van der Waals forces.

Secondary bonding. Part 8. The crystal and molecular structure of diphenyl telluroxide
TL;DR: The crystal and molecular structure of diphenyl telluroxide has been determined by X-ray diffraction at room temperature as mentioned in this paper, and the structure was refined to a final R 0.038 for 1 910 independent reflections (four-circle diffractometer measurements).
