- A hexavalent neptunium-237 stock solution was prepared by a technique that included anion-exchange purification from possible inorganic admixtures followed by precipitation of the oxalate of tetravalent Np in order to avoid any organics. Dissolution and destruction of the oxalate complex were carried out in concentrated nitric acid, and then the solution was evaporated up to wet salts and dissolved in distilled water. The reduction of hexavalent to pentavalent neptunium was performed by adding a NaNO2 solution 2 M, Then an excess of concentrated NH4OH was added to precipitate NPO2OH, which was used as a neptunium precursor. The precipitate was centrifuged and washed by distilled water five times. For synthesis, NpO 2OH was dissolved in 0.1 M picolinic acid. Then diguanidinium carbonate neutralized by picolinic acid and NaNO2 was added. A compound was obtained during isothermal evaporation at 22°C of the mixture with a molar r
- 2 was added. A compound was obtained during isothermal evaporation at 22°C of the mixture with a molar ratio of Np/guanidinium/Pic/Na equal to 1:1: 2:5.

- The data were collected on a Bruker KAPPA APEX II diffractometer with a CCD area detector using graphite monochromated Mo Kα (λ, 0.710 73 Å) radiation. A single crystal was mounted on a glass fiber and transferred to the goniometer for data collection. The crystal was cooled to 100 K under a cold nitrogen gas stream. The structure was solved using the SHELXTL software package, and absorption corrections were made with SADABS. The structure was refined by full-matrix least squares on F2. All of the non-H atoms were readily located, and their positions were refined anisotropically. H atoms were refined isotropically. Main crystallographic data: M, 679.39, space group P1, a, 8.9329(1) Å, b, 11.6669(2) Å, c, 11.6698(2) Å, α, 68.080(1)°, β, 88.213(1)°, γ, 73.254(1)°, V, 1076.45(3) Å3, Z, 2, number of reflections, 21 93

- NIR and IR spectra were measured using Shimadzu UV3100 and Specord M80 spectrometers, respectively. Samples of ∼2 wt, of the solids were prepared in NaCl pellets. Selected frequencies (cm-1) of the IR spectrum and their assignments: 3460s, 3412s, υ(NH2, 3236s, 3216s, υ(CH, 1660sh, 1652m, υ(C=O, 1582vs, υas(NO 2, 1560vs, υas (COO, 1476m, υ(CN)Pyr; 1408 vs, 1396sh, υ5(COO, 1376sh, υas(NO2, 1262-1120m, ρ(CH)Pyr; 812vs, γ(CH)Pyr, υ(NpO2, 674m, 636m, δ(COO, 544m, δ(NO2, 464w, ρNO2
