Abstract Symmetrical anhydrides of hydroxycarbene complexes of manganese and rhenium, [π-C5H5(CO)2MC(R)]2O, (M = Mn, Re) are prepared by reaction of cationic carbyne complexes [π-C5H5(CO)2MCR]BX4 with the corresponding metal carbonyl acylates Li[π-C5H5(CO)2MC(O)R]. [π-C5H5(CO)2MnC(C6H5)]2O is also obtained by controlled hydrolysis of π-C5H5(CO)2MnCX(Br)Ce6H5. The new complexes are characterized spectroscopically and by an X-ray structure analysis of [π-C5H5(CO)2MnC(C6H5)2O.

The elastic properties of rutile transition metal dioxides XO2 ( X = Ru , Rh , Os , and Ir ) are investigated using first-principles calculations based on density functional theory. Elastic constants, bulk modulus, shear modulus, and Young's modulus as well as Possion ratio are given. OsO 2 and IrO 2 show strong incompressibility. The hardness estimated for these dioxides shows that they are not superhard solids. The obtained Debye temperatures are comparative to those of transition metal dinitrides or diborides.
