General Description
Ammonium oxalate monohydrate is a diammonium salt of oxalic acid. Its refined crystal structure has been investigated by three-dimensional diffraction studies. Influence of bivalent [Mn(II), Co(II), Ni(II)] and trivalent cations [Fe(III), Cr(III)] impurities on the growth rates of ammonium oxalate monohydrate crystals has been described. Its space group and unit cell parameters have been analyzed by neutron diffraction studies. Its IR spectra have been compared with that of isolated coal-solubilizing agent (CSA).
Purification Methods
Crystallise it from water (10mL/g) at 50o. [Beilstein 2 IV 1846.]
Check Digit Verification of cas no
The CAS Registry Mumber 6009-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,0 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6009-70:
(6*6)+(5*0)+(4*0)+(3*9)+(2*7)+(1*0)=77
77 % 10 = 7
So 6009-70-7 is a valid CAS Registry Number.

EPR and optical study of Mn2+ doped ammonium oxalate monohydrate
Kripal, Ram,Mishra, Vishal
, p. 699 - 704 (2005)
Studies on fine and hyperfine structures of paramagnetic resonance spectra in single crystals of Mn2+: ammonium oxalate monohydrate are reported. As sufficient numbers of lines were not obtained at room temperature, measurements have been done at liquid nitrogen temperature and at the frequency of X-band. The Mn2+ spin Hamiltonian parameters have been evaluated employing a large number of resonant line positions observed for various orientations of the external magnetic field and the surrounding crystalline field has been discussed. The values of the zero field parameters that give good fit to the observed EPR spectra have been evaluated. The values obtained for g, A, B, D, E and a are 2.0002±0.0002, (100±2)×10 -4, (79.5±2)×10-4, (257±2)×10-4, (85±2)×10-4 and (-18±1)×10-4 cm-1, respectively. The percentage of covalency of the metal-ligand bond is also determined. The optical absorption study has been done at room temperature. The observed bands are assigned as transitions from the 6A1g(S) ground state to various excited quartet levels of Mn2+ ion in a cubic crystalline field. The electron repulsion parameters (B and C), the crystal field splitting parameter(Dq) and the Trees correction (α) providing good fit to the observed optical spectra have been estimated and the values obtained for the parameters are B=897, C=2144, Dq=910 and α=76 cm-1.
