41. The ruthenium diamine complexes form adducts with guanine. 42. Its structure consists of a tetramer, very similar to that of ruthenium pentafluoride. 43. Potassium ruthenate may be synthesized by reacting ruthenium metal with potassium hydroxide and potassium nitrate. 44. Ruthenium dioxide with lead and bismuth ruthenates are used in thick-film chip resistors.45. Like the other metals of the platinum group, ruthenium is inert to most chemicals. 46. Taube researched ruthenium and osmium, both elements have a high capacity for back bonding. 47. It can contain osmium, rhodium, iridium, and iron substituting for the ruthenium . 48. A collaboration with J�ns Jakob Berzelius nearly led to the discovery of ruthenium in 1828. 49. "Syntheses of neutral iron, ruthenium , and manganese half-sandwich vinylidene complexes. 50. NAMI-A and KP1019 are based primarily around the use of the metal ruthenium .
