摘要

> Metathesis of the isomorphous 15‐metallacrown‐5 complexes {[LnCu 5 (GlyHA) 5 (SO 4 )(H 2 O) 6.5 ]} 2 (SO 4 ) · 6H 2 O (Ln III = Pr, Nd, Sm, Eu; GlyHA 2– = glycinehydroxamate) with excess p ‐bdc 2– ( p ‐bdc 2– = terephthalate) gave pairs of isomorphous complexes {[LnCu 5 (GlyHA) 5 (CO 3 )(H 2 O) 4 ] 2 ( p ‐bdc)} · 15H 2 O [Ln = Pr ( 1 ) and Nd ( 2 )] and {[LnCu 5 (GlyHA) 5 (SO 4 )(H 2 O) x ] 2 ( p ‐bdc)} · y H 2 O [Sm ( 3 ) x = 5, y = 12; Eu ( 4 ), x = 4, y = 14] as outcomes of partial sulfate replacement. Complexes 1 – 4 are discrete dimers with two 15‐metallacrown‐5 blocks {LnCu 5 } 3+ , a bridging p ‐bdc 2–
