Early metal di- and tricyanometalates: Useful building blocks for constructing magnetic clusters
Treatment of mer-VCl3(THF)(3) with KTp* [Tp* = hydridotris(3,5dimethylpyrazol-1.yl)borate], followed by [NEt4]CN in acetonitrile, affords [NEt4](Tp*)V-III(CN)3](H2O)-H-. (1(.)H20); aerobic oxidation affords [NEt4][(Tp*)V-IV(O)(CN)(2)] (2). Subsequent treatment of 2 with Mn-II(OTf)(2) (OTf = trifltuoromethanesulfonate) and 2,2'-bipyridine affords {[(Tp*)V(O)(CN)(2)](2)[Mn-II(biPY)(2)](2)[OTf](2).}(.)2MeCN (3). Magnetic measurements indicate that 1-3 exhibit S = 1, 1/2, and 4 spin ground states, respectively.
