Abstract

In 2-(2′-pyridyl)phenyltellurium(II) bromide ( 1) the coordination about tellurium may be described as pseudo-trigonal bipyramidal wth bromine (TeBr = 2.707(11) Å) and nitrogen (TeN) = 2.236(11) Å) atoms occupying axial positions. The equatorial plane comprises a carbon atome (TeC = 2.111(6) Å) and two lone pairs of electrons. There are no significant intermolecular interactions between the six independent molecules in the unit cell. Bis[2-2′-pyridyl)phenyltellurium(II) chloride]· p-ethoxy-phenylmercury(II) chloride ( 2) may be regarded as an “inclusion compound” obtained by replacement of two RTeX (X = Cl or Br) molecules by two p-ethoxyphenylmercury(II) chloride entities. There is approximately linear coordination about mercury (CHgCl = 179.2°(4), Hg-C = 2.044(14) and HgCl = 2.328(4) Å) and 2-(2′-pyridyl)phenyltellurium(II) chloride, with a structure similar to that of ( 1) above (TeN = 2.2366(6), TeCl = 2.558(1), TeC = 2.080(25) Å). There are no significant intermolecular contacts.
