The asymmetric unit of the title compound, C38H34Cl2O2Te2·H2O, contains two independent TeIV cations, each coordinated by three phenyl ligands, two Cl− anions and one acetic acid molecule in a distorted octahedral 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 molecule bridge the two independent TeIV cations, forming the dimeric complex molecule, in which the Te...Te separation is 3.7314 (4) Å. In the crystal, the water molecules of crystallization link the TeIV complex molecules into chains running along the b-axis direction via O—H...O and O—H...Cl hydrogen bonds.
