Abstract:The
formation of pseudocapsule type homo- and heteromultinuclear
complexes of calix[6]-mono-crown-5 (H4
L) encapsulating from 4 to 6 alkali metal ions is reported.
H4
L reacts with KOH to yield a hexanuclear
potassium(I) complex [K6(HL)2(CH3OH)2]·CHCl3 (1) in
which two bowl-shaped tripotassium(I) complex units are linked in
a rim-to-rim fashion via the interligand C–H···π
interactions. In the same reaction condition, RbOH afforded a tetranuclear
rubidium(I) complex [Rb4(H2
L)2(CH3OH)2(μ-H2O)2]·6CHCl3 (2). In 2… Show more
