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 .

Subphthalocyanines, lower homologs of phthalocyanines, show great promise for applications in many fields of contemporary research such as non-linear optics, donor-acceptor systems for photovoltaics, photodynamic therapy and anion sensing. This short review gives a brief overview of the latest developments in the chemistry, characterization, self-organization, properties and applications of this fascinating molecule.

5-[4-(1,2,4-Triazol-4-yl)phenyl]-1H-tetrazole, C9H7N7, (I), an asymmetric heterobifunctional organic ligand containing triazole (tr) and tetrazole (tz) termini linked directly through a 1,4-phenylene spacer, crystallizes in the polar space groupPc. The heterocyclic functions, serving as single hydrogen-bond donor (tz) or acceptor (tr) units, afford hydrogen-bonded zigzag chains with no crystallographic centre of inversion. In the structure ofcatena-poly[[diaquacadmium(II)]bis{μ2-5-[4-(1,2,4-triazol-4-yl)phenyl]tetrazol-1-ido-κ2N1:N1′}], [Cd(C9H6N7)2(H2O)2]n, (II), the CdIIdication resides on a centre of inversion in an octahedral {N4O2} environment. In the equatorial plane, the CdIIpolyhedron is built up from four N atoms of two kinds, namely oftrans-coordinating tr and tz fragments [Cd—N = 2.2926 (17) and 2.3603 (18) Å], and the coordinating aqua ligands occupy the two apical sites. The metal centres are separated at a distance of 11.1006 (7) Å by means of the double-bridging tetrazolate anion,L−, forming a chain structure. The water ligands and tz fragments interact with one another, like a double hydrogen-bond donor–acceptor synthon, leading to a hydrogen-bonded three-dimensional array.
