The structural and spectroscopic characterisations of fac-[Re(phen)(CO)3Cl] (1) (phen = 1,10-phenanthroline), fac-[Re(ephen)(CO)3Cl] (3) [ephen = 5,6-epoxy-1,10-phenanthroline (2)] and ephen are reported. The appearance of weak hydrogen bond networks in the crystal lattice of [Re(ephen)(CO)3Cl] and ephen are discussed. Two different isomers of [Re(ephen)(CO)3Cl] were identified by IR and NMR spectroscopy
fac-[Re(phen)(CO)3Cl] (1) (phen = 1,10-菲咯啉), fac-[Re(ephen)(CO)3Cl] (3) [ephen = 5 ,6-epoxy-1,10-phenanthroline (2)] 和 ephen。讨论了 [Re(ephen)(CO)3Cl] 和 ephen 晶格中弱氢键网络的出现。[Re(ephen)(CO)3Cl] 的两种不同异构体通过 IR 和 NMR 光谱进行鉴定。通过温度依赖性 NMR 光谱区分这些复合物的重合共振。粗物质的重结晶允许两种异构体的分离。光谱数据允许计算与能隙定律一致的辐射和非辐射发光速率常数。(© Wiley-VCH Verlag GmbH & Co.
