Reactivity of [M4(co)12(µ-pyms)4] (M = Mn, re; pymS = pyrimidine-2-Thiolate) with bis(triphenylphosphino)nickel(ii) dicarbonyl: X-ray crystal structure of [Re(Co)3(κ2-pymS)(PPh3)]

The reaction between the tetranuclear compound [Mn 4 (CO) 12 (-pymS) 4 ] (1) and (PPh 3 ) 2 Ni(CO) 2 at room temperature resulted in the cleavage of the square to afford the dinuclear complex [Mn 2 (CO) 5 (-pymS) 2 (PPh 3 )] (2) (19%) along with two mononuclear complexes fac-[Mn(CO) 3 (κ 2 -pymS)(PPh 3 )] (3) (43%) and [Mn(CO) 2 (κ 2 -pymS)(PPh 3 ) 2 ] (4) (24%). In contrast, a similar reaction of [Re 4 (CO) 12 (-pymS) 4 ] (5) with (PPh 3 ) 2 Ni(CO) 2 at 25 o C did not afford any dinuclear
