Supramolecular architectures in cadmium (II) - thiocyanate complex of 2-amino 4,6-dimethyl pyrimidine

Abstract

In this complex, {catena- poly cadmium (II) -di-µ-thiocyanato] bis (2-amino-4,6-dimethylpyrimidine [CdAMPY]},
the asymmetric unit contains, 2-amino-4,6-dimethylpyrimidium cation, a thiocyanato ion, 2 –isocyanate ion (one in the axial
& one in the equatorial position) and a cadmium ion occupying a crystallographic inversion centre. The environment around
cadmium atom is octahedral. The 2-aminopyrimidine cations are not coordinated to cadmium but are hydrogen bonded to
the thiocyanato ions. Symmetry related pyrimidines interact via N-H…N hydrogen bonds, forming a typical ring motif with
graph set notation R
2
2 (8). The crystal structure is further stabilized by N-H...S hydrogen bonds.
