A vezetéskutatás relevanciája

A legtöbb menedzser vallja magáénak azt a véleményt, hogy csak az a kutatás hasznos, amely azonnali segítséget tud nekik nyújtani. A tanulmány azonban rámutat arra, hogy a magas színvonalú kutatás haszna valóban csak sokkal később jelentkezik, bizonyára azért, mert olyan kérdésekkel foglalkozik, amely tényleg fontos, szemben azzal, amely a felületes szemlélő számára az adott időpontban fontosnak tűnik. A szerző végül egy átfogóbb és érvényesebb fogalmat alakít ki a relevanciáról, amely az elméletnek megfelelő helyet jelöl ki

Di-μ-chlorido-bis­[dichlorido(3,3′,5,5′-tetra­methyl-4,4′-bipyrazol-1-ium-κN 2′)copper(II)] dihydrate

The structure of the centrosymmetric title compound, [Cu2Cl6(C10H15N4)2]·2H2O, consists of a dimeric [{(HMe4bpz)CuCl3}2] unit (HMe4bpz is 3,3′,5,5′-tetra­methyl-4,4′-bipyrazol-1-ium) with two solvent water molecules. Each [HMe4bpz]+ cation is bonded to a CuCl3 unit through a Cu—N dative bond, effectively making square-planar geometry at the Cu atom. Two of these units then undergo a face-to-face dimerization so that the Cu atoms have a Jahn–Teller distorted square-pyramidal geometry with three chlorides and an N atom in the basal plane and one chloride weakly bound in the apical position. Several N—H⋯Cl, O—H⋯Cl and N—H⋯O hydrogen bonds form a three-dimensional network

2,2′-Biimidazolium hexa­aqua­manganese(II) bis­(sulfate)

The title compound, (C6H8N4)[Mn(H2O)6](SO4)2, was obtained by cocrystallization of 2,2′-biimidazolium sulfate and bis­(tetra­butyl­ammonium) tetra­chlorido­manganate(II). The asymmetric unit contains one isolated (SO4)2− anion, one half of an octa­hedral [Mn(H2O)6]2+ dication and one half of a 2,2′-biimidazolium dication, each of which lies on an inversion centre. Mol­ecules are connected by a three-dimensional N—H⋯O and O—H⋯O hydrogen-bond network

2-Oxo-1,2-dihydro­pyrimidin-3-ium di-μ-chlorido-bis­{dichloridobis[pyrimidin-2(1H)-one-κN 3]cuprate(II)} dihydrate

The asymmetric unit of the title compound, (C4H5N2O)2[Cu2Cl6(C4H4N2O)2]·2H2O, consists of one cation, one half of a centrosymmetric dianion and one water mol­ecule. The centrosymmetric dianion formed by dimerization in the crystal structure has neutral pyrimidin-2-one ligands coordinated to each copper(II) centre through Cu—N bonds. The Cu atoms each have a distorted trigonal bipyramidal geometry, with the N atom of the pyrimidin-2-one ligand in an axial position, and dimerize by sharing two equatorial Cl atoms. N—H⋯Cl, O—H⋯Cl and N—H⋯O hydrogen bonds connect the anions, cations and water mol­ecules, forming a three-dimensional network

Two-step solid-state synthesis of PEPPSI-type compounds

peer-reviewedThe two-step mechanochemical preparation of carbene–pyridine complexes of palladium and platinum is reported. The organometallic products, which represent a class of commercially available catalysts, are rapidly formed in excellent yield proving solvent-free synthesis to be a viable synthetic alternative even in the case of NHC-containing compounds
