Chemical compound

cis-Dichlorobis(bipyridine)ruthenium(II) is the coordination complex with the formula RuCl2(bipy)2, where bipy is 2,2'-bipyridine. It is a dark green diamagnetic solid that is a precursor to many other complexes of ruthenium, mainly by substitution of the two chloride ligands. The compound has been crystallized as diverse hydrates.

Synthesis and structure

The complex is prepared by heating a DMF solution of ruthenium trichloride and bipyridine.

With octahedral coordination geometry, the complex exists exclusively as the chiral cis isomer. The corresponding Ru(III) salts are also known.

  • Yes, there have been recent discussions and findings related to the Byblos Necropolis Graffito. The Byblos Necropolis Graffito is an ancient Phoenician inscription discovered in the 14th-century BCE city of Byblos, Lebanon. Here are some recent updates:

    1. In 2019, a team of researchers from the University of California, Berkeley, published a paper on the graffito's linguistic and historical significance. They found that the inscription is actually a metrical composition in Phoenician, depicting the story of a ritual performed by the Phoenician queen, Dowager Queen Tibni-milkab-tasmet.

    2. In 2020, archaeologists from the Lebanese Directorate-General for Antiquities announced the discovery of new underground structures and a cache of Phoenician artifacts during excavations at the Byblos Necropolis. The finds included pottery, jewelry, and other artifacts dating back to the 14th and 13th centuries BCE.

    3. The Byblos Museum, which houses many artifacts from the Byblos Necropolis, has been undergoing renovations and has recently opened new exhibits showcasing the history and significance of the site. Visitors can now explore interactive displays, including a re-creation of the Phoenician city and a chance to see the Byblos Necropolis Graffito firsthand.

    4. The graffito's significance extends beyond its historical importance. In 2020, the International Phoenician Festival was held in Byblos, celebrating Phoenician culture and heritage. The event included re-enactments of Phoenician rituals and traditions, as well as concerts, workshops, and exhibitions showcasing Phoenician art, music, and cuisine.

    These recent discussions, discoveries, and events demonstrate the ongoing interest in the Byblos Necropolis Graffito and its significance to our understanding of Phoenician culture and history.
