H. Adams et al., CIS-DERIVED AND TRANS-DERIVED CHAIN STACKING IN BIS(HEXAFLUOROACETYLACETONATO)METAL(II) TETRAMETHYLPYRAZINE COMPLEXES, Inorganica Chimica Acta, 209(1), 1993, pp. 55-60
The reaction of metal(II) hexafluoroacetylacetonates (meta]=Mn(II), Fe
(II), Co(II), Ni(II), Cu(II), Zn(II)) with tetramethylpyrazine is repo
rted. The X-ray crystal structures of [Mn(hfac)2]2(tmp)3.4H2O and Co(h
fac)2(tmp).4H2O are reported and reveal the formation of chain polymer
s through second sphere cis- and trans-derived stacking, respectively.
