Abstract
Solid state techniques involving pressure and temperature have been used to synthesize the fluoride member of the CuX2(pyrazine) (X = F, Cl, Br) family of coordination polymers that cannot be crystallized by solution methods. CuF2(pyrazine) exhibits unique trans doubly-bridged Cu–F2–Cu chains that provide an opportunity to quantify magnetic superexchange in an isostructural Cu–X2–Cu series.
