Syntheses, structures, and magnetic characterization of dicyanometalate(ii) building blocks: [NEt4][(Tp*)MII(CN)2] [MII = Cr, Co, Ni; Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate]

Abstract

The syntheses and structures of three dicyanometalate(II) complexes, [NEt₄][(Tp*)M^II(CN)₂]·nMeCN·½Et₂O (M^II = Cr, 1, n = ½; Co, 2, n = 1; Ni, 3, n = 1) are described; magnetic studies indicate that 3 is diamagnetic while 1 and 2 are paramagnetic high- and low-spin S = 2 and ½ complexes, respectively.
