摘要
The syntheses, crystal structures, magnetic and luminescent properties of three isornorphous compounds [LnIII6（,u4-O）2（C4A）2- （NO3）2（HCOO）2（CH30）2（DMF）4（CH3OH）4] （Ln = Gd （1）, Tb （2） and Dy （3）; H4C4A = p-tert-butylcalix[4]arene） are reported. These three compounds are featured with the sandwich-like units constructed by two tail-to-tail calixarene molecules and an in-between Lnm6 octahedron. The DyTM compound exhibits both single molecule magnet behavior and photoluminescence.
The syntheses, crystal structures, magnetic and luminescent properties of three isomorphous compounds [Ln III 6 (μ 4-O) 2 (C4A) 2-(NO 3 ) 2 (HCOO) 2 (CH 3 O) 2 (DMF) 4 (CH 3 OH) 4 ] (Ln = Gd (1), Tb (2) and Dy (3); H 4 C4A = p-tert-butylcalix[4]arene) are reported. These three compounds are featured with the sandwich-like units constructed by two tail-to-tail calixarene molecules and an in-between Ln III 6 octahedron. The Dy III compound exhibits both single molecule magnet behavior and photoluminescence.
