A New Coordination Polymer Based on Citric Acid Containing 1D [Ag]∞ Chain with Strong Ag–Ag Bonding Interaction

详细

A new polynuclear silver complex Ag₆(W₂O₅)(Cid)₂ based on citric acid is obtained by hydrothermal method and studied by single crystal X-ray diffraction compound The compound crystallizes in triclinic space group P\(\bar {1}\), Z = 1. The structure solution is complicated by two component non-merohedral twinning. The structure feature is a 3D framework containing 1D infinite [Ag]_∞ chains. Ag atoms are connected by metal–metal bonding interaction with the Ag–Ag distances of 2.849(3)–3.218(2) Å.
