Introduction

Analysis of the Interaction between Adenine Nucleobase and Metal‐Malonato Complexes

“…The IR spectra (KBr pellets) were recorded with a FTIR 8400S Shimadzu spectrometer in the 4000-400 cm -1 spectral region. Magnetic measurements were performed on polycrystalline samples of the complexes taken from the same uniform batches used for the structural determinations with a Quantum Design SQUID susceptometer covering the temperature range 5.0-300 K at a magnetic field of 1000 G. The susceptibility data were corrected for the diamagnetism, as estimated from Pascal's tables, [32] the temperature-independent paramagnetism and the magnetisation of the sample holder.…”

E.P.R. study of dimeric forms of Cu(II)-monoazaporphyrin and of the radical cations of Cu(II) octaethylporphyrin and -octaethylchlorin

“…magnetic field H was 15.3 K Gauss and the quantity H dH/dz = 17 • l0 s Gauss2/cm. The temperature dependence of the molar susceptibility X.~I is given by [8] …”

Modulating the MII/Pyrimidine‐4,6‐dicarboxylato System by Metal, Solvent and Temperature Variation

“…Thermal analyses (TG/DTA) were performed with a TA Instruments SDT 2960 thermal analyzer in a synthetic air atmosphere (79 % N 2 /21 % O 2 ) with a heating rate of 5°C·min -1 . Magnetic measurements were performed on polycrystalline samples of the complexes with a Quantum Design SQUID susceptometer covering the temperature range 5-300 K at a magnetic field of 1000 G. The susceptibility data were corrected for the diamagnetism estimated from Pascal's Tables [52] the temperature-independent paramagnetism, and the magnetization of the sample holder. [Cu(μ-pmdc)(DMSO) 2 ] n (6): H 2 pmdc ligand (0.0183 g, 0.09 mmol), Cu(NO 3 ) 2 ·3H 2 O (0.0110 g, 0.045 mmol), dimethyl sulfoxide (2.5 mL), and concentrated HNO 3 (20 μL) were added to a vial.…”
