carbyne complexes of tungsten, L(CO)2WCR/Ar, 1b–7b, where R=CH3, Ar=substituted phenyl, and LH=(2-hydroxyphenyl)-bis(3,5-dimethylpyrazolyl)methane, with L− being a tridentate, uninegative ligand, were synthesized from W(CO)6 via tetraethylammonium acylmetallate salt, as thermally stable and air-stable solids. In another complex, 8b, the aryl ring is complexed with tricarbonylchromium. Crystal structure
