prop-2-yn-1-ol and alkynediol transition metal complexes of Pt and Ni has been examined in light of the intermolecular interactions and hydrogen-bonding patterns established by alkyne monoalcohols and diols in the solid state. The analysis has been based on the crystal structure determination of the alcohols 1,1-dimethyl-3-tert-butylprop-2-yn-1-ol (1), tert-butylbis(ethyl)prop-2-yn-1-ol (2), tert-butylcyclohexylprop-2-yn-1-ol
已经根据炔烃一元醇和固态二醇建立的分子间相互作用和氢键模式,研究了Pt和Ni的丙-2-炔-1-醇和炔二醇过渡金属配合物的固态超分子组装。该分析基于醇1,1-二甲基-3-叔丁基丙-2-炔-1-醇(1),叔丁基双(乙基)丙-2-炔-1-醇的晶体结构测定醇(2),叔丁基环己基丙-2-炔-1-醇(3)和四甲基炔二醇(4)以及双(叔丁基环己基丙-2-炔-1-醇)M(0) (M = Pt(6a)和Ni(6b)和双(叔丁基环戊基丙-2-炔-1-醇)Pt(0)(7),并与剑桥结构数据库中的可用数据集成在一起。已经显示,最常见的氢键模式是基于-OH基团的四聚体,其形成正方形,菱形或开放蝶形,而与分子复杂性无关。根据prop-2-yn-1-ol上取代基的空间体积,可建立更大的环系或链。分子间和分子内氢键的距离已显示出取决于醇的类型,差异主要源于空间。研究了炔烃与金属中心配位后,C⋮C键的拉曼/ IR拉伸频率变
