μ-Bis(diphenylphosphino)ethane-P,P′-bis[bis(O-isopropyldithiocarbonato-S,S′)zinc(II)]

“…Thus, isolated monomeric species are formed upon chelation with 1,10-phenanthroline (Klevtsova et al, 2001). In the same way, isolated dimeric units are found in the 1:2 adduct with 4,4′-bipyridyl, in which the latter is bidentate bridging (Klevtsova et al, 2000). As a continuation of previous studies in this area (Tiekink, 2001a,b;Jie & Tiekink, 2002;Dee & Tiekink, 2002), the title compound, (µ-Ph 2 PCH 2 CH 2 PPh 2 ) {Zn(S 2 COiPr) 2 } 2 , (I), has been investigated.…”

“…One possible advantage of disrupting the extended arrays is to provide more suitable precursors for chemical vapour deposition studies (e.g. Zeng, Hampden-Smith & Larson, 1994;Klevtsova et al, 2001), as well as by us (e.g. Consequently, there have been a number of recent investigations into adduct formation of such species by various groups (e.g.…”

“…In the case of Zn(S 2 CO i Pr) 2 , both mononuclear and binuclear adducts have been characterized. In this way, 1,10-phenanthroline mononuclear species are found in the two polymorphs (see below) that have been characterized crystallographically (Klevtsova et al, 2001). By contrast, with the bidentate ligand 4,4 H -bipyridine (as a dichloromethane solvate: Klevtsova et al, 2000), a dinuclear species with ®ve-coordinated zinc centres has been found.…”

A similar result occurs when bis(diphenylphosphino)ethane (Beer et al, 2002) is used as the lewis base.…”
