Coordination properties of 1,3-benzothiazoles. Formation of a polymeric complex with square-planar coordination around the copper(II) ion in the reaction of CuCl2·6H2O with 1,2-bis[2-(1,3-benzo-thiazol-2-yl)phenylthio]ethane

It is shown that a coordination polymer is formed by the reaction of 1,2-bis[2-(1,3-benzothiazol-2-yl)-phenylthio]ethane with copper(II) chloride in a mixture of ethanol and chloroform at room temperature. The structure of the polymer has been determined by X-ray crystallography. The copper atom in the coordination polymer has a square-planar ligand environment and is coordinated to the nitrogen atoms of the benzothiazole rings of two different molecules of ligand and two chloride anions.

Study of the Zn-porphyrin structure by fluorescence spectroscopy methods

Results of investigation of the optical properties of zinc complexes of mesotetraphenylporphyrin and monopyridyltriphenylporphyrin in impurity-free organic solvent are presented. Analyses of absorption and emission spectra and fluoresence decay kinetics in terms of both a sum of exponentials and using simulation of energy-transformation processes in a tetramer-type Zn-porphyrin complex compound are carried out.

Fifty Years of Inorganic Biomimetic Chemistry: From the Complexation of Single Metal Cations to Polynuclear Metal Complexes by Multidentate Thiolate Ligands

This article covers 50 years of coordination chemistry of transition metal complexes and metal-sulfur aggregates involving thiolate-incorporating ligands by reviewing selected examples. The studies in the coordination chemistry of sulfur-rich ligands have been undoubtedly triggered and fed by the concomitant development of bioinorganic chemistry, particularly of iron-sulfur enzymes. The review is broken down in five sections, which examine complexes of increasing nuclearity, including binuclear complexes based on compartmental macrocyclic ligands. We show also how ligand engineering has allowed the researchers in the field to control the nuclearity of the complexes, which was a particularly difficult task for sulfur-based ligands, as thiolates show a strong tendency to coordinate to more than one metal cation at once.     

Contrarian investment strategy with data envelopment analysis concept

One of the typical issues in financial literature is that the market tends to be overly pessimistic about value stocks, many of which are past losers. Therefore, over-reactions might capture by measuring earnings surprise vary with past return levels. In this paper, we propose a new index for an effective investment strategy to capture the return-reversal effect using both Data Envelopment Analysis (DEA) and Inverted DEA in order to consider the above characteristics of the market. Our investment strategy using the new index exhibits better performance than the naive return-reversal strategy that only uses past returns or earnings surprise. In addition, the correlations between our new index and commonly used value indices are insignificant, and the value indices cannot represent the over-valued (under-valued) situations perfectly. Hence, considering both proposed and value indices like book-to-price one, we could select value stocks more effectively than by using only one of these indices.

Zur Kristallchemie der Oxometallate des Hafniums

On the Crystal Chemistry of Oxometallates of Hafnium The contribution shows Hf⁴⁺ in oxides and oxometallates with typical and untypical coordination by oxygen. First of all the HfO6‐octahedra exist besides the Oxides of Hafnium in different Hf‐molybdates and ‐vanadates. A special feature is the formation of complex surroundings of to each other isolated HfO₆‐octahedra, forming [HfO₃(Mo₆O₂₁)]⁸⁻‐, [HfO₃(Mo₁₂O₃₉)]⁸⁻‐ and [HfO₃(Rb₂O₁₅)]³⁰⁻‐groups. HfO₆‐octahedra are incorporated in polyhedra chains too. Interesting points of view of the crystal chemistry of Hf‐oxometallates are Hf/O‐polyhedra showing coordination numbers C.N. > 6. For example two times capped trigonal prisms (hp/ht‐HfMo₂O₈) and three times capped trigonal prisms ht/hp‐HfO₂ (Cottunnit‐Type) are representative polyhedra with C.N. = 8 and C.N. = 9. In the fluorite related compounds (Ca₂Hf₇O₁₆) Hf⁴⁺ is situated inside a damaged cube (one corner is missing). At least hexagonal HfO₁₂‐antiprisms (C.N. = 12) had been found in one of the trigonal form of HfMo₂O₈. In the same crystal structure it shows (C.N. = 6) trigonal HfO₆‐Prismens. Hf⁴⁺ has in addition no problems to accept statistical distributions with other elements. It adapts crystal structures of pyrochlores and perowskites of different distortion. Finally one compound, nearly free of oxygen (Hf₉Mo₄NiO_0,84) is reported, it shows interesting metal clusters.

Optimal proportional reinsurance and investment with multiple risky assets and no-shorting constraint

In this paper, the basic claim process is assumed to follow a Brownian motion with drift. In addition, the insurer is allowed to invest in a risk-free asset and n risky assets and to purchase proportional reinsurance. Under the constraint of no-shorting, we consider two optimization problems: the problem of maximizing the expected exponential utility of terminal wealth and the problem of minimizing the probability of ruin. By solving the corresponding Hamilton–Jacobi–Bellman equations, explicit expressions for their optimal value functions and the corresponding optimal strategies are obtained. In particular, when there is no risk-free interest rate, the results indicate that the optimal strategies, under maximizing the expected exponential utility and minimizing the probability of ruin, are equivalent for some special parameter. This validates Ferguson’s longstanding conjecture about the relation between the two problems.     

An optimal insurance strategy for an individual under an intertemporal equilibrium

In this paper, we discuss how a risk-averse individual under an intertemporal equilibrium chooses his/her optimal insurance strategy to maximize his/her expected utility of terminal wealth. It is shown that the individual’s optimal insurance strategy actually is equivalent to buying a put option, which is written on his/her holding asset with a proper strike price. Since the cost of avoiding risk can be seen as a risk measure, the put option premium can be considered as a reasonable risk measure. Jarrow [Jarrow, R., 2002. Put option premiums and coherent risk measures. Math. Finance 12, 135-142] drew this conclusion with an axiomatic approach, and we verify it by solving the individual’s optimal insurance problem.
