A mesoporous ionic solid with 272 AuI6AgI3CuII3 complex cations in a super huge crystal lattice

Abstract

Here, we report a unique mesoporous ionic solid (I) generated from a cationic AuI6AgI3CuII3 dodecanuclear complex with D-penicillamine depending on the homochirality and crystallization conditions. I crystallizes in the cubic...

Serendipitous formation of oxygen-bridged CuII6M (M = MnII, CoII) double cubanes showing electrocatalytic water oxidation

“…As part of our study on the preparation of heterometallic coordination compounds with S-containing amino acids, 9 here, we report heterometallic double-cubane clusters of [Cu 6 M(µ 3 -OH) 6 (µ 3 -Br) 2 ( d -pends) 3 ] (M = Mn II ( 1 Mn ), Co II ( 1 Co ); d -H 2 pends = d -penicillaminedisulfide) with an Mn II /Co II ion at the centre of the structure, which are analogous to the homometallic copper( ii ) double-cubane cluster of [Cu 7 (µ 3 -OH) 6 (µ 3 -Br) 2 ( d -pends) 3 ] ( 1 Cu ) previously reported by us. 10 Clusters 1 Mn and 1 Co were unexpectedly produced by the moderate reaction of [Cu 2 Pt 2 (NH 3 ) 4 ( d -pen) 4 ] ( d -H 2 pen = d -penicillamine) 11 with MBr 2 in water (Scheme 1).…”
