文摘
A novel complex [Ag(ptac)]∞ (1) (ptac = tBuC(O)CHC(O)CF3) has been prepared by interaction of Ag2O and Hptac, its structure being elucidated by single crystal X-ray diffraction. The complex has a chain polymeric structure originating from tetradentate-μ-bridging coordination of the ptac ligands and interactions Ag–Cγ between adjacent {Ag(ptac)} fragments. The coordination environment of the silver atom is a distorted square pyramid. The distances Ag–O are 2.362(10)-2.600(10) Å; Ag–Cγ–2.32(2) Å and 2.328(13) Å; Ag···Ag–3.3497(13) Å and 3.3750(13) Å; the values of chelate angles OAgO fall within 64.6(4)-71.1(3)°. Under thermogravimetric experiment conditions compound 1 decomposes within temperature range 100-385°С with formation of silver metal.
