چکیده
The [Os(III)(CN)6]3- anion is prepared by chemical oxidation in aqueous solution and isolated as yellow prisms of [Ph4P]3[Os(III)(CN)6].6H2O (1). This species crystallizes in the triclinic space group P with cell parameters a = 13.7609(11) A, b = 16.2275(13) A, c = 17.0895(14) A, alpha = 91.4040(10) degrees , beta = 109.3600(10) degrees , gamma = 102.3970(10) degrees , V = 3497.4(5) A(3), and Z = 2. The slightly distorted octahedral moiety displays Os-C and C-N bond lengths that average 2.058 and 1.146 A, respectively. Spin-orbit-coupling splitting of the ground-state term dominates the NIR region of the electronic spectrum and the magnetic behavior of 1. The experimental information points to higher spin delocalization over the coordinated cyanides than in [Fe(III)(CN)6]3-.

First Principle Study of MC (M= Al, Ga, and In) at Equilibrium and under Negative Stress
The electronic and magnetic properties of the hypothetical compounds of MC (M=Al, Ga and In) are investigated by using first-principle calculations and pseudopotential plane wave self-consistent field method based on density functional theory. In order to find the most stable phase of MC (M=Al, Ga and In), we study them in zinc-blende (ZB), rocksalt (RS), wurtzite and NiAs crystal structures. W...

متن کاملDensity Functional Studies on Crystal Structure and electronic properties of Potassium Alanate as a candidate for Hydrogen storage
Potassium Alanate is one of the goal candidates for hydrogen storage during past decades. In this report, initially the Density Functional Theory was applied to simulate the electronic and structural characteristic of the experimentally known KAlH4 complex hydride. The relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
