Poly[bis(piperazine-1,4-diium) [(μ₄-cyclo-hexaphosphato)dilithium] tetrahydrate]

Abstract

In the title compound, {(C4H12N2)2[Li2(P6O18)]·4H2O}n, the phosphate ring anion, located around an inversion center, adopts a chair conformation. Adjacent P6O18 rings are linked via corner-sharing by LiO4 tetra­hedra, generating anionic porous {[Li2(P6O18)]4−}n layers parallel to (101). The piperazine-1,4-diium cations occupy the pores and develop hydrogen bonds with the inorganic framework. An extensive network of N—H⋯O and O—H⋯O hydrogen-bonding inter­actions link the components into a three-dimensional network and additional stabilization is provided by weak C—H⋯O hydrogen bonds.

Synthesis, crystal structure and characterization of two new organic bismuthate(III) compounds: [C6H18O]2Bi2X10·2H2O (X = Br, Cl)

“…. Geometrical parameters of the N-(2-hydroxyethyl)piperazine-1,4-diium dications are found to be in agreement with those reported in related piperazine-1,4-diium salts and its derivatives [14]. The conformation of the piperazine six-membered ring can be described in terms of Cremer and Pople puckering coordinates [15], i.e., evaluating the parameters Q (total puckering amplitude), q 2 , q 3 , h and u.…”

A Hirshfeld surface analysis, crystal structure and infrared characterization of a new organic cyclohexaphosphate, (C8H12N)4(Li)2(P6O18)(H2O)6

“…This paper relates a contribution to the study of cyclohexaphosphates including organicmonovalent cations. Up to now, only four examples of this type of compound are reported [5][6][7][8]. Here, we report on the synthesis of a new cyclohexaphosphate with formula (C8H12N)4(Li)2(P6O18)(H2O)6.…”

Structural, NMR, IR, Hirshfeld surface, electrochemical and in vitro biochemical investigations of a new organic cyclohexaphosphate, (C6H6ClFN)4 (Li)2(P6O18)(H2O)4

“…Cyclohexaphosphates were shown to be potentially attractive as precursors in the solidstate synthesis of simple and mixed-cation polyphosphates for glass making [7,8]. In this area, the literature reports several cyclohexaphosphates of mixed cations associating the lithium molecules which have been known and structurally characterized [9][10][11][12][13]. This family of compounds which exhibit a rich structural diversity can be further used in lithium batteries [14].…”
