The preparation, magnetic properties, electronic and infrared spectra, and molecular structure of poly-bis(μ-diethylphosphinato)copper(II) are described. Crystals of poly-bis(μ-diethylphosphinato)copper(II) are triclinic, a = 7.700(1), b = 9.807(1), c = 10.101(1) Å, α = 90.48(1), β = 104.77(1), γ = 112.21(1)°, Z = 2, space group [Formula: see text]. The structure was solved by direct methods and was refined by full-matrix least-squares procedures to R = 0.025 and Rw = 0.032 for 3491 reflections with I ≥ 3σ(I). The polymeric structure consists of Cu atoms with flattened tetrahedral coordination geometry linked by double phosphinate bridges. Mean bond lengths (corrected for libration) are: Cu—O, 1.924(3), P—O, 1.526(4), and P—C, 1.807(4) Å. Assignment of the electronic spectrum using a crystal field model gives Dq = 1665 cm−1 and Cp = 1800 cm−1. Magnetic susceptibility studies give no evidence for magnetic concentration over the temperature range 80 to 300 K.

Synthesis of nanoparticles doped with various ions can significantly expand their functionality. The conditions of synthesis exert significant influence on the distribution nature of doped ions and therefore the physicochemical properties of nanoparticles. In this paper, a correlation between the conditions of synthesis of manganese-containing cadmium sulfide or zinc sulfide nanoparticles and their optical and magnetic properties is analyzed. Electron paramagnetic resonance was used to study the distribution of manganese ions in nanoparticles and the intensity of interaction between them depending on the conditions of synthesis of nanoparticles, the concentration of manganese, and the type of initial semiconductor. The increase of manganese concentration is shown to result in the formation of smaller CdS-based nanoparticles. Luminescent properties of nanoparticles were studied. The 580 nm peak, which is typical for manganese ions, becomes more distinguished with the increase of their concentration and the time of synthesis.
