摘要: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) Neodymium mIknatIslar 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 http://turkey.chinamagnets.biz 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.
