[Ni(CO2)(PCy3)2],0·75(C7H8), where Cy = cyclohexyl, can be made either by treating [Ni(PCy3)3] or [{Ni(PCy3)2}2N2] with CO2 in toluene, direct reduction of [NiBr2(PCy3)2] sodium sand under CO2; the complex is planar, ligand possesses bent geometry and co-ordinated through carbon atom one oxygen atoms.
The paper summarises the experience gained by writers in interpretation of cone penetration test (CPT) and flat dilatometer (DMT) for assessment geotechnical properties sands. In first part paper, problem determining relative density (DR) as function results ambient stress (σ'), silica sands, is dealt with. second peak angle shearing resistance (φ'p) attention given to use Bolton's strength-dilatancy theory order estimate φ'p. Engineering correlations, based on work, are proposed allowing...

A Pt6 octahedron surrounded by a second containing 38 Ni atoms forms the metal framework of cluster ions [Ni38Pt6(CO)48H6−n]n− (n=3–6), which are easily synthesized from [Ni6(CO)12]2−, PtCl2, and H+. Such clusters molecular models for "cherry" crystallites, known catalyst research.
Zinc ion fluorescence sensing and the binding properties of 4-methyl-2,6-bis(((phenylmethyl)imino)methyl)phenol (HL) have been investigated. It displays high selectivity for Zn2+ can be used as zinc ion-selective luminescent probe biological application under physiological conditions. The increase in emission presence is accounted by formation hexanuclear complex [Zn6(L)2(OH)2(CH3COO)8] characterized X-ray crystallography. An approximately 6-fold Zn2+-selective chelation-enhanced response...

Understanding the mechanisms that control hydraulic and semipermeable membrane behavior of enhanced bentonites (EBs), which comprise natural montmorillonite amended with polymers or organic compounds, is important for assessing long-term performance engineered barriers manufactured from these materials. Accordingly, available experimental evidence EBs was critically interpreted through a theoretical framework, allows macroscopic transport swelling properties chemically active clays to be...

Reaction of the electron-rich derivative cis-[Pt(Me)2(DMSO)2] with 2,2′-bipyridine (L) affords mononuclear "rollover" N′,C(3) cyclometalate [Pt(L-H)(Me)(DMSO)] (1a) or unusual dinuclear species [Pt2(μ-L-2H)(Me)2(DMSO)2] (2a), depending on Pt/L molar ratio.

A novel dioxo-bridged dinuclear gold(III) complex with two 2,9-dimethylphenanthroline ligands was synthesized and thoroughly characterized. Its crystal structure solved, its solution behavior assessed. Remarkably, this compound revealed excellent antiproliferative properties in vitro against a wide panel of 36 cancer cell lines, combining high cytotoxic potency to pronounced tumor selectivity. Very likely, these arise from an innovative mode action (possibly involving histone deacetylase...
A single-crystal X-ray analysis has shown the [Fe4(CO)13H]– anion to contain a butterfly arrangement of metal atoms; twelve carbonyl groups are terminally bonded, three each iron atom, whereas thirteenth group interacts with all four atoms and behaves as four-electron ligand.
