The first series of cyclometalated ruthenium complexes with a CCC-pincer bis-carbene ligand have been obtained as bench-stable compounds. Single-crystal X-ray analysis of one of these complexes with 4'-di-p-anisylamino-2,2':6',2''-terpyridine is presented. The Ru(II/III) redox potentials and MLCT absorptions of these complexes can be varied by attaching an electron-donating or -withdrawing grou...

Aimed at creating a true photoswitchable energy transfer system, four dinuclear complexes containing ruthenium(II) and osmium(II) metal centers bridged by spiropyran-type linkers were designed and investigated. The bridge in its closed spiropyran form was shown to be a good insulator for energy transfer between the Ru-bpy donor and the Os-bpy acceptor (bpy = 2,2'-bipyridine). On the basis of pr...

This Article contains an error in Figure 2c, where the y-axis 'μ g [Ru]/mg [cell protein]' is incorrectly labelled as 'ng [Ru]/mg [cell protein]'. The correct Figure 2c appears below as Figure 1.

This speech addressed itself to the variety of achievement motivations that can be critically different for men and women. The author, impressed by the different wars people cognitively define and experience a successful accomplishment, developed a taxonomy of psychological 'cues which people might use in defining their success. Six varieties of achievement motivation were reviewed: (1) autonom...

Assume that a1j 6= 0 for j = 2 . . . n. Then the (1, 1) element of A∗A is equal to a11+a12+. . .+a1n. The (1, 1) element of AA∗ is equal to a11. Since A is normal, a 2 11 + a 2 12 + . . . + a 2 1n = a 2 11 and, therefore, a1j = 0 for j = 2 . . . n. Now assume that a2j 6= 0 for j = 3 . . . n. Using the above proven fact that a12 = 0 we can compare the (2,2) entries of A∗A and AA∗ to show that al...

OBJECTIVES To evaluate the micro-tensile bonding strength (muTBS) of three luting resins to human regional dentin. METHODS Dentin disks from non-carious third molars were prepared from different regions (s, superficial dentin; d, deep dentin; c, cervical dentin), and divided into groups based on anatomical locations and luting resins (Super-Bond C&B: SB; Panavia F 2.0: PF; RelyX Unicem: RU): ...

Interactions between three hexacationic arene ruthenium metallaprisms, [(p-cymene)6Ru6(tpt)2(dhnq)3](6+), [(p-cymene)6Ru6(tpt)2(dhbq)3](6+) and [(p-cymene)6Ru6(tpt)2(oxa)3](6+), and a series of human proteins including human serum albumin, transferrin, cytochrome c, myoglobin and ubiquitin have been studied using NMR spectroscopy, mass spectrometry and circular dichroism spectroscopy. All data ...

Vinylidene ruthenium complexes were prepared from trichloronitrosylbis(phosphine)rutheniums and terminal alkynes, subsequent cycloaddition of methyl propiolate to the vinylidene complexes giving rise to unusual ruthenacyclobutene species; in these transformations, an interesting electrostructurally-flexible behaviour of the NO ligand was observed.

Ruthenium nitrosyl complexes are fascinating versatile photoactive molecules that can either undergo NO linkage photoisomerization or NO photorelease. The photochromic response of three ruthenium mononitrosyl complexes, trans-[RuCl(NO)(py)₄]2+, trans-[RuBr(NO)(py)₄]2+, and trans-(Cl,Cl)[RuCl₂(NO)(tpy)]⁺, has been investigated using density functional theory and time-dependent density functional...

The reaction of metallothionein-2 (MT-2) with the organometallic antitumour compound [Ru(η(6)-p-cymene)Cl(2)(pta)], RAPTA-C, was investigated using ESI MS and ICP AES. The studies were performed in comparison to cisplatin and significant differences in the binding of the two complexes were observed. RAPTA-C forms monoadducts with MT-2, at variance with cisplatin, that has been observed to form ...
