- Abstract
- Modification of the nickel dithiolate metalloligand, Ni(bme-daco) [where bme-daco ) bis(mercaptoethyl)-diazacyclooctane] or Ni-1, by oxygenation of one thiolate into a sulfinate, Ni(mese-daco) [where mese-daco )(mercaptoethyl)(sulfinatoethyl)diazacyclooctane] or Ni-2, restricts the ligating ability to monodentate and is expectedto reduce the donor ability of the remaining thiolate S. Nevertheless, the Ni-2 complex forms a stable thiolate S-bound adduct of W0(CO)5, (Ni-2)W(CO)5, a complex whose î(CO) IR spectrum reports insignificant differences in the donor abilities of Ni-1 and Ni-2 in (è1-NiN2S2)W(CO)5 complexes. In the presence of the strong sulfophile CuI, a CuNi2 trimetallic, (Ni-2)2CuBr, was isolated. Another trimetallic, (í-è2-Ni-1)[W(CO)5]2, demonstrated the Ni(bmedaco), Ni-1, unit to bridge low-valent metals in a transoid configuration, yielding W-W distances of over 5 Å.
