The tetradentate ligand 2,3,4,5-tetra(pyrid-2-yl)cyclopent-2,4-dien-1-one (3) was prepared and used for the synthesis of the dinuclear chelates [μ-(3)(MX2)2] (MX2 = BeCl2, ZnCl2, ZnBr2, HgCl2, HgBr2); the closely related BeCl2 chelate of the bidentate ligand 2,5-diphenyl-3,4-di(pyrid-2-yl)cyclopent-2,4-dien-1-one (1) was also prepared. The structures of these compounds were determined by X-ray crystallography
制备了四齿配体 2,3,4,5-tetra(pyrid-2-yl)cyclopent-2,4-dien-1-one (3) 并用于合成双核螯合物 [μ-(3) (MX2)2] (MX2 = BeCl2, ZnCl2, ZnBr2, HgCl2, HgBr2); 还制备了双齿配体 2,5-二苯基-3,4-二(吡啶-2-基)环戊-2,4-二烯-1-酮 (1) 的密切相关的 BeCl2 螯合物。这些化合物的结构由 X 射线晶体学确定,并与相应的未螯合类似物 [(py)2MX2](py = 吡啶)的结构进行比较。对于晶体中的 [μ-(3)(HgCl2)2],观察到通过氯桥键聚合成聚合物链。
