“…505 The layered gallophosphate Ga 4 P 4 O 16 (EtNO 2 ) 4 (MU-32) was studied by 1 H, 13 C and 31 P MAS NMR spectroscopy. 506 Similar data were reported for the novel species Ga 13 (PO 4 ) 18 (C 6 H 14 N) 13 507 6 ] Á 8H 2 O, where L = 1,4-dimethylpiperazine. 508 19 F, 31 P and 71 Ga MAS NMR spectra gave structural information for a hybrid open-framework fluorinated gallium oxalate-phosphate templated by 1,3-diaminopropane.…”

“…These encompass structures of isolated units, chains, layers, and frameworks, most of which represent their own unique structure type (although a few isotypic structures are found, as can be seen from the unit cell parameters in Table 4.3). For instance, the layers in phosphato-glycine-gallium (Hasnaoui et al 2005) differ significantly from those found in sulfato-glycinedi-lithium (Fleck and Bohatý 2004;Fig. 4.7).…”

Salts of Amino Acids

In this chapter we present salts composed of amino acids combined with inorganic cations and anions. These salts generally contain amino acids in neutral, i.e., zwitterionic form, with the charges balanced by the cations and anions. However, some of the phases resented here contain cations, anions, and amino acids, but the amino acids are not in neutral form, as, e.g., glycinate À Cu, but for reasons of similarity, they are included in this chapter. The variation of salts (and thus the number of species) is even greater as for salts of amino acids and cations, as a multitude of combinations of amino acids, cations, and anions is possible. Additionally, different hydration states are often found, as well as different ratios of components. Thus, there are several instances of systems containing more than one phase (e.g., the system glycine-zinc-chloride-water). Despite the greater variation, many coordination patterns found in the salts described in the previous chapter recur in the salts reported here. Likewise, the connectivities of units are similar as those found in salts of amino acids and cations. Instances of materials with noteworthy physical properties are presented. Keywords Introducing RemarksAs stated before, this chapter deals with salts of amino acids and neutral, inorganic salts. In these species, the amino acid usually exists in zwitterionic form, but it is still coordinated to a cation. As other anions are present, the amino acids are not the only possible ligands. These anions can act as additional ligands (plus possible water molecules as well). Moreover, in some cases the inorganic anions are not part of the coordination spheres, but located in the interstices between units composed of cations and coordinating amino acids.M. Fleck and A.M.

“…8, 9 After the synthesis, it is observed in the pores of the material and can sometimes be bound to the inorganic framework via T-N or T-O-C bonds (T = Zn, Ga, ...). [9][10][11][12] Such connections between inorganic and organic parts are also observed in the oxalatephosphate systems (Ga-O-C bonds) and for phosphonate materials where a P atom is directly linked to a carbon atom (belonging to R group) in PO 3 R. 13,14 Histidine is one of the essential amino acids. In the monomeric form, it is a polydentate ligand which can coordinate to metal centers (e.g., Zn, Cu, Ni, Co, V) through the imidazole, the amino, and/or the carboxyl groups.…”

A new layered zinc phosphate (Mu-39) has been synthesized by hydrothermal treatment with biomolecules as original templates. It was synthesized with the L-histidine amino acid (C 6 H 9 N 3 O 2 ). The structure was determined by a single crystal X-ray diffraction study combined with exhaustive solid-state NMR experiments. These last ones [ 1 H f 13 C HETCOR, 1 H single quantum/double quantum (DQ), 31 P, 1 H f 31 P CPMAS, 1 H f 31 P HETCOR] ascertained the formulation of Mu-39 as {[C 6 H 10 N 3 O 2 þ ][Zn 2 (HPO 4 )(PO 4 ) -] 3 H 2 O} n with a hydrogen phosphate and phosphate ligands, and ruled out partial protonation such as (H 1-x PO 4 )(H x PO 4 ). A 31 P magic angle spinning (MAS) NMR study supported the almost complete racemization of L-histidine during the hydrothermal synthesis with only a small enantiomeric excess of 25% remaining. The compound crystallizes in the triclinic symmetry (space group P1) with a = 8.6109(6) Å , b = 9.0319(6) Å , c = 9.9523(7) Å , and R = 84.481(2)°, β = 83.279(2)°, γ = 74.652(2)°, V = 739.56(9) Å 3 , Z = 2. The inorganic layer is built up from four-membered rings sharing T-O-T bonds (T = Zn and P) and connected to each other in order to form ladders which are joined together via a Zn-O-P bond for creating eight-membered rings. The interest and the originality of this new zinc phosphate come especially from its unusual stability in aqueous solution.
