Design and synthesis of new luminescent coordination networks of sql topology showing the highest degrees of interpenetration

Abstract

A new β-diketone ligand of nanometric length (HL), whose crystal structure shows a distance of 23 Å between two peripheral nitrile groups, has been employed with silver(I) to assemble 2D...

2D → 3D polycatenated Zn(ii) metal–organic framework with good chemical stability as a fluorescent sensor toward salicylaldehyde, acetylacetone and H2PO4−

“…1b). The 3D polycatenated structure with a degree of catenation of 2 and an index of separation of 1 is formed by π-π stacking [41][42][43][44] (Fig. 1c).…”

Solvent effect in the chemical design of coordination polymers of various topologies with Co2+ and Ni2+ ions and 2-furoate anions

“…Odd degrees of interpenetration are in general rare and 7-fold interpenetration is the first observed for etb. 44,48,49 All the networks are related by the translations [11 ¯1 ¯], [121 ¯] and [2,1,1] in the trigonal system. In the topological databases, 71 examples of standard representation of coordination compounds and valence-bonded MOFs with etb topology are presented and only one compound, [Ag(L)](CF 3 -SO 3 )•0.5CHCl 3 (L = N-naphthylmetyl-N,N-bis(4-pyridylmethyl) amine), has an entanglement which is 2-fold interpenetration.…”

“…The topological analysis of crystal structures was performed using the program package ToposPro (https:// topospro.com/), web service TopCryst (https://topcryst.com/) and RCSR database (https://rcsr.net/). [42][43][44][45][46][47][48][49][50][51]…”
