In the title centrosymmetric Ru-II mononuclear complex, trans-Ru(PPh3)(2)(3
,5-Me(2)pz)(2)Cl-2 (pz = pyrazole), [RuCl2(C5H7N2)(2)-(C18H15P)(2)], the Ru
-II ion exhibits an octahedral coordination environment, consisting of the
two trans P atoms of PPh3, the two trans N atoms of 3,5-Me(2)pz and the two
trans Cl atoms. The 3,5-Me-2 pz ligands coordinate terminally to the centr
al Ru-II ion.
