Supramolecular assemblies of p-sulfonatocalix[4]arene with aquated trivalent lanthanide ions

PdII, ZnII and AgI Complexes of Tetrakis(N‐7‐azaindolyl)benzene: Variation of Bonding Modes, Extended Structures and Luminescence

“…Extended structures involving metal complexes and organic molecules linked by hydrogen bonds have been reported previously. [8] One important feature of 4 is that the hydrogen-bonded 1D chains are helical and rotate in the same direction in the crystal lattice, resulting in the forma- …”

A novel 2D coordination polymer based on a copper(II) tetramer with p -sulfonated thiacalix[4]arene

“…the longest Cu-O bond being ca. 0 6. A longer than the shortest one and the longest Cu-S bond being ca.…”

“…They can be designed with the sites available for metal binding on the upper and lower rim, as well as at the linker positions, and with ring sizes and conformations that could be used to influence the topolopy and function of networks formed. There are a few examples in which calixarenes of any sort participate in coordination polymers [1][2][3][4][5][6]. A new class of macrocycles, thiacalix [4]arenes (2) has been recently reported [7].…”

Lanthanide compounds containing a benzo-15-crown-5 derivatised [60]fullerene and the related [Tb(H2O)3(NO3)2(acac)]·C14H20O5supramolecular adduct

“…2.42 Å (Table 2) and consistent with the values reported for related structures. 5,7,[34][35][36][37] These coordinated water molecules are further involved in five strong homonuclear O-HÁ Á ÁO hydrogen bonds (Table 3) with two neighbouring benzo-15-crown-5 molecules, leading to the formation of a zigzag supramolecular one-dimensional tape (Fig. 4) in which the Tb(1)Á Á ÁTb (1) i distance is 8.8236(15) Å (symmetry code used to generate equivalent atoms: ) that superimpose a large broad band in the ultraviolet-blue spectral region (250-400 nm).…”
