A series of ML(2) coordination compounds of manisyl-substituted 2-pyridin-2-yl-1,10-phenanthrolines (pherpys) and 2,2':6',2''-terpyridines (terpys) with Fe(ii), Co(ii), Ni(ii), Cu(ii), Zn(ii), Ru(ii), and Os(ii), were synthesized. The pyridyl-phenanthroline-metal complexes form isomorphous crystals (space group Pcca), except for the zinc complex, which is isostructural but not isomorphous (space group P2(1)/c). Traces of the Ru complex induce the Zn complex to crystallize in the Pcca modification. Terpyridine complexes are isostructural but divided into two subgroups (Pnna and C2/c). Within the crystal lattice, the dications arrange into two-dimensional sheets of interdigitated left- and right-handed double helices via CHpi and pi-pi interactions of the pendant manisyl functionalities. All of the complexes exhibit weak ligand charge transfer (LCT) emission in solution at room temperature and the osmium complexes possess an emissive metal to ligand charge transfer (MLCT) state.
一系列 ML(2)配位化合物的亚甲基取代 2-吡啶-2-基-1,10-菲咯啉 (pherpys) 和 2,2':6',2''-三联吡啶 (terpys) 与 Fe(ii), Co(ii), Ni(ii), Cu(ii), Zn(ii), Ru(ii), 和 Os(ii) 被合成。吡啶-菲咯啉-金属配合物形成同构晶体(空间群 Pcca)，除了锌配合物，它是同构但不同质的(空间群 P2(1)/c)。钌配合物的痕迹诱导锌配合物以 Pcca 修饰结晶。三联吡啶配合物是同构的，但分为两个亚组(Pnna 和 C2/c)。在晶格中，二阳离子通过悬挂的亚甲基官能团的 CHpi 和 pi-pi 相互作用排列成二维交错的左手和右手双螺旋状薄片。所有配合物在室温下的溶液中都表现出弱的配体电荷转移(LCT)发射，并且锇配合物具有发射性的金属到配体电荷转移(MLCT)态。
