The preparation of several new trans-bis-1-alkynyl(phthalocyaninato)silicon (VIc—f), -germanium (VIIc—f) and -tin (VIIId, f) compounds as well as trans-bis-1-alkynyl(hemiporphyrazinato)germanium (XIc, e, f) derivatives is described. The products were obtained in high yields by treating the corresponding dichlorides (I, II, IV, X; X = (Cl) with 1-alkynyl Grignard reagents (Vc—f) in tetrahydrofuran (THF) and were characterized spectroscopically. The compounds obtained are considered as models for a new kind of one-dimensional conductor.
