Abstract

The asymmetric unit of the title compound, C38H34Cl2O2Te2·H2O, contains two independent Te(IV) cations, each coordinated by three phenyl ligands, two Cl(-) anions and one acetic acid mol-ecule in a distorted octa-hedral C3Cl2O geometry; the longer Te⋯Cl distances ranging from 3.2007 (11) to 3.4407 (11) Å and the longer Te⋯O distances of 3.067 (3) and 3.113 (3) Å indicate the weak bridge coordination. The Cl(-) anion and acetic acid mol-ecule bridge the two independent Te(IV) cations, forming the dimeric complex mol-ecule, in which the Te⋯Te separation is 3.7314 (4) Å. In the crystal, the water molecules of crystallization link the Te(IV) complex mol-ecules into chains running along the b-axis direction via O-H⋯O and O-H⋯Cl hydrogen bonds.
