Raman spectroscopic study of two dimensional polymer compounds of 2-aminopyrimidine

The Raman spectra of the two dimensional layered polymer compounds, M(2APM)2M′(CN)4 {where M=Mn or Cd; and M′=Ni or Pt; 2APM=2-aminopyrimidine} are reported in the 70-4000 cm−1 region. Vibrational data suggests that compounds are similar in structure to the Hofmann type two dimensional coordination polymer compounds, formed with M′(CN)4−2 ions bridged by M(2APM)2+2 cations. 2-Aminopyrimidine was coordinated to M(II) through one of the nitrogen atom of its heterocycle ring. Vibrational assignments are given for the bands arising from the tetracyanometallate layers and coordinated 2APM.
