Abstract
The crystal structures of 1-phenyl-4,6-dimethylpyrimidine-2-thionetetraaquacobalt(II) dinitrate (I)a=9.032(2),b=12.458(2),c=18.067(3)Å,β=103.25(3)°,Z=4;P21/c,R=0.049; 1-phenyl-4,6-dimethylpyrimidine-2-thione (II)a=12.005(3),b=10.090(2),c=9.649(2)Å,β=104.4(1)°,Z=4;P21/n,R=0.038; and 4,6-dimethylpyrimidine-2-thione (III)a=15.485(3),b=13.255(3),c=7.127(2)Å,β=104.3(1)°,Z=8,C2/c,R=0.041 are reported. In (I) the coordination around the cobalt(II) is distorted octahedral involving one ligand moleculevia sulphur and nitrogen atoms and four water molecules. It is relevant that the parameters in the complexed ligand are not different from those found in the uncomplexed one (II), excepting the distances on the nitrogen atom directly involved in the coordination. Bond distances and angles in compound (III) agree with those found in (II).
