We present a rare intramolecular Au···H–C(sp3) hydrogen-bonding interaction and luminescent properties of a gold(I) carbene complex. The Au(I) complex [(L)Au(I)Cl] (1), where L= N-(9-anthracenyl)-N′-(heptyl)benzimidazol-2-ylidene, was prepared, and thermal, emission, and lifetime properties along with a density functional theory study have been considered. X-ray diffraction analysis of single crystals evidenced the solid-state structure of gold complex 1, which exhibited the expected linear coordination geometry. The n-heptane arm of Lmodulates the hydrogen-bonding interaction between Au(I) and the hydrogen atom of one of the CH2moieties. The packing of the gold(I) carbene complex shows an interesting one-dimensional column in the solid state due to intermolecular Cl···H interactions. The blue emission of 1in the 400–560 nm region has been tentatively ascribed to arise from intraligand and gold transitions, but the hydrogen-bonding interactions may also make partial contributions. |
