Grow slow : The usual direct treatment of MeLi and CuSPh did not yield X‐ray quality crystals of MeCu(SPh)Li. An indirect method starting from Me 2 CuLi ⋅ LiSPh and chalcone afforded the desired crystals by the slow reaction of the intermediate π‐complex (see scheme). This strategy produced the first X‐ray crystal structure of a Posner cuprate. A complementary NMR study showed that the contact ion pair was also the main species in solution.
