Reaction of a methanolic suspension of CuCOCl with histamine (hm) at 0°C gives a solution from which [Cu(hm)CO]BPh4[νCO(Nujol) 2091 cm–1] is recovered, while a methanolic suspension of CuI in the presence of histamine reversibly absorbs carbon monoxide [1 CO per Cu] giving [Cu2(hm)3(CO)2]2+; X-ray analysis of [Cu2-(hm)3(CO)2](BPh4)2[νCO(Nujol) 2055 and 2066 cm–1] shows the presence of a dimeric cation with one histamine chelated to each copper, and the other one bridging the two metal atoms.

Abstract
Reaction of a methanolic suspension of CuCOCl with histamine (hm) at 0°C gives a solution from which [Cu(hm)CO]BPh4[νCO(Nujol) 2091 cm–1] is recovered, while a methanolic suspension of CuI in the presence of histamine reversibly absorbs carbon monoxide [1 CO per Cu] giving [Cu2(hm)3(CO)2]2+; X-ray analysis of [Cu2-(hm)3(CO)2](BPh4)2[νCO(Nujol) 2055 and 2066 cm–1] shows the presence of a dimeric cation with one histamine chelated to each copper, and the other one bridging the two metal atoms.File in questo prodotto:
