The title compound, [(eta (5)-C5H5)Ni(S)PPh2](2) or [Ni-2(C5H5)(2)-(C12H10P
S)(2)], consists of two (eta (5)-C5H5)Ni moieties bridged by the P and S at
oms of two [Ph2P(S)](-) ligands, forming a nonplanar Ni-S-P-Ni-S-P twist-bo
at heterocycle. The average Ni-P and Ni-S bond lengths are 2.1498 (6) and 2
.1983 (5) Angstrom, respectively.
