Abstract

Silver malate [Ag₂(mal)] (1) (mal = O₂C–CH₂–CH(OH)–CO₂) with a polymeric structure is prepared and characterized by elemental analysis and IR spectroscopy. This complex can be dissolved upon heating in pyridine (py) or its derivatives. Crystals of the [Ag₂(py)₄(mal)]·H₂O (2a), [Ag₂(3-Me-py)₄(mal)] (3a) and [Ag₂(4-Me-py)₄(mal)]·0.6(4-Me-py) (4a) coordination polymers are prepared from solutions. The crystals can be characterized by XRD but undergo rapid degradation and pyridine loss when extracted from the mother liquor or slightly heated. The desolvation and decoordination of 2a, 3a, 4a yields [Ag₂(py)₂(mal)] (2), [Ag₂(3-Me-py)₃(mal)] (3), [Ag₂(4-Me-py)₃(mal)] (4), respectively, as stable products.

基于苹果酸银的链式mof

制备了具有聚合物结构的苹果酸银[Ag2(mal)] (1) (mal = O2C-CH2-CH (OH) -CO2)，并用元素分析和红外光谱对其进行了表征。该配合物可在吡啶（py）或其衍生物中加热溶解。在溶液中制备了[Ag2(py)4(mal)]·H2O （2a）、[Ag2(3-Me-py)4(mal)] （3a）和[Ag2(4- me -py)4(mal)]·0.6(4- me -py) （4a）配位聚合物晶体。该晶体可以用XRD表征，但从母液中提取或稍微加热时，会发生快速降解和吡啶损失。2a、3a、4a的解溶和配位分别得到[Ag2(py)2(mal)](2)、[Ag2(3- me -py)3(mal)](3)、[Ag2(4- me -py)3(mal)](4)作为稳定产物。
