Crystal structure of a low-temperature (100 K) polymorph of catena-poly[(μ2-4,4′-bipyridine-κ2 N,N′)-bis(O,O′-diethyldithiophosphato-κ1 S)zinc(II)], C18H28N2O4P2S4Zn

“…Finally, in an accompanying report, a low temperature (100 K) polymorph for {Cd[S 2 P(OEt) 2 ] 2 (4,4′bipy)}n was described [13]. This, as was the room temperature (293 K) form [14], is a linear coordination polymer with a trans-N 2 S4 coordination geometry for the cadmium(II) centre.…”
