centrosymmetric four- and eight-membered rings, respectively; the quin/nitrate adduct is more complex, also binuclear but with bis(chelating) nitrate. AgNO3:py (1:3) is found to be binuclear, while with Agtfa/py, a 3:2 adduct [Ag(py)2][Ag2(tfa)3](∞|∞) is found with a novel, polymeric, strongly interacting anion. A further pair of 1:3 adducts, AgNO3:2np (2np = 2-aminopyridine) and Agtfa:nmp, both mononuclear [AgL3]+X−
摘要记录了合成的单晶X射线结构表征和振动光谱研究,研究了碱度不同的含氧阴离子(高氯酸盐,硝酸盐,羧酸盐(如三氟乙酸盐(≡' tfa'))),具有在甲基(2-)或有时在6-)位置受甲基或非配位官能团阻碍的各种吡啶(≡'py')或哌啶(≡'pip')碱基其他类型的配体是2-甲基吡啶('2mp'),2,6-二甲基吡啶('lut'),2,4,6-三甲基吡啶('coll'),喹啉('quin'),2 2,6,6-四甲基哌啶('tmp'),2-氨基-,6-甲基吡啶('nmp'),2-甲氧基吡啶('mop')和2-氰基甲基吡啶('pcn'); 研究还记录了与母体“ py”,碱和4-氰基吡啶(“ cnp”)的加合物。在大多数配合物中,NAgN基序占主导地位,这可能是由于氮碱和任何附近的阴离子或溶剂分子的(竞争性)碱度变化而线性不同地引起的。在高度受阻的tmp / tfa加合物中发现了一个不寻常的变化,它是
