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.
标题化合物C38H34Cl2O2Te2·H2O的不对称单元包含两个独立的Te(IV)阳离子，每个阳离子在扭曲的八面体C3Cl2O几何构型中由三个苯基配体、两个Cl(-)阴离子和一个乙酸分子配位；较长的Te⋯Cl距离在3.2007 (11)至3.4407 (11) Å之间，较长的Te⋯O距离为3.067 (3)和3.113 (3) Å，表明存在弱桥连配位。Cl(-)阴离子和乙酸分子桥连两个独立的Te(IV)阳离子，形成二聚体络合物分子，其中Te⋯Te间距为3.7314 (4) Å。在晶体中，结晶水分子通过O-H⋯O和O-H⋯Cl氢键将Te(IV)络合物分子连接成沿b轴方向延伸的链。
