Anionic tris (biimidazolate) nickelate (II) ([Ni(Hbim)3]−), which is a hydrogen-bonding (H-bonding) molecular building block, undergoes self-organization into honeycomb-sheet superstructures connected by complementary intermolecular H-bonds. The crystal obtained from the stacking of these sheets is assembled into channel frameworks, approximately 2 nm wide, that clathrate two cationic K+-crown ether derivatives organised into one-dimensional (1D) double-columnar arrays. In this study, we have shown that all five cationic guest-included crystals form nanochannel structures that clathrate the 1-D double-columnar arrays of one of the four types of K+-crown ether derivatives, one of which induces a polymorph. This is accomplished by adaptably fitting two types of anionic [Ni(Hbim)3]−host arrays. One is a network with H-bonded linkages alternating between the two different optical isomers of the and types with flexible H-bonded [Ni(Hbim)3]−. The other is a network of a racemate with 1-D H-bonded arrays of the same optical isomer for each type. Thus, [Ni(Hbim)3]−can assemble large cations such as K+crown-ether derivatives into double-columnar arrays by highly recognizing flexible H-bonding arrangements with two host networks of and .

The unexpected title compound, [Cu(C6H8NO6)Cl(H2O)]·C12H24O6·3H2O, was synthesized by crystallization of a mixture containing CuCl2·2H2O, nitrilotriacetic acid (H3NTA), KOH, 18-crown-6 and GdCl3·6H2O. The complex consists of a hydrogen-bonded polymeric structure, in which discrete Cu(H2NTA)(H2O)Cl units interact via the carboxyl groups and the coordinating water molecules with the crown ether molecules. No direct metal–crown ether bond exists in the infinite sandwich-type hydrogen-bonded structure. The copper complex lies on a mirror plane, which passes through Cu and all the coordinating atoms. The crown ether molecule lies on an inversion centre. One water molecule is disordered across the mirror plane.
