The chemistry of the heterobinuclear platinum-iridium complex [PtIr(CO)3(μ-dppm)2][PF6], 1, dppm = Ph2PCH2PPh2, is described. The reaction of a hydride with 1 gave [HPtIr(CO)2(μ-dppm)2], by displacement of the carbonyl ligand from platinum, while reaction of 1 with dihydrogen, hydrogen chloride or Ph2MeSiH gave the fluxional complex [PtIrH4(CO)(μ-dppm)2][PF6], [PtIrH2Cl2(CO)(μ-dppm)2][PF6], or ...

We investigate the computational power of C++ compilers. In particular, it is known that any partial recursive function can be computed at compile time, using the template mechanism to define primitive recursion, composition, and minimalization. We show that polynomial time computable functions can be computed at compile-time using the same mechanism, together with template specialization.

Dedicated to Professor Heribert Offermanns on the occasion of his 75th birthday The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3′′-bis(bromomethyl)-m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ ,μ-tpsac)]2, [Ru2(CO)4(μ ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2...

Abstract. The rank of a skew partition λ/μ, denoted rank(λ/μ), is the smallest number r such that λ/μ is a disjoint union of r border strips. Let sλ/μ(1 ) denote the skew Schur function sλ/μ evaluated at x1 = · · · = xt = 1, xi = 0 for i > t. The zrank of λ/μ, denoted zrank(λ/μ), is the exponent of the largest power of t dividing sλ/μ(1 ). Stanley conjectured that rank(λ/μ) = zrank(λ/μ). We sho...

The reaction of Ap(9Me)Lu(CH2SiMe3)2(thf) (Ap(9Me) = (2,4,6-trimethylphenyl)[6-(2,4,6-triisopropylphenyl)pyridine-2-yl]amido ligand) with two molar equivalents of PhSiH3 affords a trinuclear alkyl-hydrido cluster [(Ap(9Me)Lu)3(μ(2)-H)3(μ(3)-H)2(CH2SiMe3)(thf)2]. The analogous reactions with Ap(9Me)Ln(CH2SiMe3)2(thf) (Ln = Y, Yb) are more complex and result in the formation of mixtures of two ty...

We define the notions of weakly μ-countably compactness and nearly denoted by Wμ-CC Nμ-CC as generalizations μ-compact spaces in sense Csaśzaŕ generalized topological spaces. To obtain a more general setting, we via hereditary classes. Using μθ-open sets, μ-regular open spaces, many results characterizations have been presented. Moreover, use properties functions to investigate effects some typ...
