Abstract

The diamagnetic complexes 1,2-C6H4(C≡CCu)2, 1,2-C6H4(C≡CCU)2·2 Pet3, 1,2-C6H4(C≡CCu)2·Pet3 (et=C2H5) and K3Cu(1,2-C6H4(C≡C)2)2 are prepared by reactions of Cul with the dipotassium salt of 1,2-diethynylbenzene o-C6H4(C≡CK)2 in liquid ammonia. The IR-active νC≡C frequencies and possible structures of the polymeric solids are discussed.
