A penta-stranded helicate was obtained by combining Pd(CHCN) with La(NO) and a polydentate ligand. The helicate displays low symmetry, both in solution and in the solid state. A dynamic interconversion between the penta-stranded helicate and a symmetrical, four-stranded helicate was achieved by adjustment of the metal-to-ligand ratio.
通过将 Pd(CHCN) 与 La(NO) 和一个多齿配体结合，得到一个五配位螺旋体。该螺旋体在溶液中和固态中都显示出低对称性。通过调节金属与配体的比例，可以实现五配位螺旋体和对称的四配位螺旋体之间的动态互变。
