Abstract:
The title compound, trans-[Ru(II)Cl(2)(N(1)-mepym)(4)] (mepym is 4-methylpyrimidine, C(5)H(6)N(2)), obtained from the reaction of trans,cis,cis-[Ru(II)Cl(2)(N(1)-mepym)(2)(SbPh(3))(2)] (Ph is phenyl) with excess mepym in ethanol, has fourfold crystallographic symmetry and has the four pyrimidine bases coordinated through N(1) and arranged in a propeller-like orientation. The Ru-N and Ru-Cl bond distances are 2.082 (2) and 2.400 (4) A, respectively. The methyl group, and the N(3) and Cl atoms are involved in intermolecular C-H...N and C-H...Cl hydrogen-bond interactions.
