spectrometry, and single-crystal X-ray analysis. The complexes show strong luminescence in the yellow–orange region in ethanol at room temperature (quantum yield is up to 22 %), and absorb light up to 550 nm with molar absorptivities of 1500–2000 M–1 cm–1. Complexes 1 and 2 possess very similar opticalproperties, whereas the introduction of the phenyl ring (complex 3) causes a hypsochromic shift (≈ 30 nm) of
