[PyNd(NO3){RuNO(NO2)4OH}2Nd(H2O)NO3]·5Py·CH2Cl2. (4):
To a mixture of solid Na2[RuNO(NO2)4OH]·2H2O (0.0414 g, 1ϫ
10–4 mol) and Nd(NO3)2·6H2O (0.0440 g, 1ϫ 10–4 mol) in dichlo-
romethane (3 mL), was added excess pyridine (0.2 mL) with stirring
over 20–30 min by 0.03 mL portions. The solid residue was filtered.
Several crystals of 4 were separated from the solution after slow
diffusion of diethyl ether into the reaction mixture over 1–2 days
at 273 K. The same technique was also applied for the cerium and
praseodymium nitrates, but only complexes 1 and 2 were separated
with yields of 30–40% and identified by elemental analysis, IR
spectroscopy, and single-crystal X-ray diffraction. All of the pre-
pared complexes slowly lose weight at room temperature, because
of removal of solvent molecules, so for thermal analysis, elemental
analysis, and magnetic measurements, we used only freshly pre-
pared samples.

Thermal Analysis: The complexes were studied with a Netzsch STA
409 PC Luxx thermoanalyzer, Al2O3 powder being used as stan-
dard. The initial weights of the samples were in the range 20–
25 mg. The experiments were run in an open alumina crucible in a
stream of helium at a heating rate of 10 K/min. The final tempera-
tures of the experiments are reported in Table 4. Analysis of ther-
mal data was performed with Proteus analysis software.[13]

Magnetic Measurements: Magnetic measurements on polycrystal-
line samples were carried out with a SQUID (Quantum Design)
magnetometer at the 5 K and room temperature in an external
magnetic field of up to 40 kOe.
Single-Crystal and Powder X-ray Diffraction Analysis: Single crys-
tals of complexes 1–5 suitable for X-ray diffraction analysis were
obtained by slow diffusion of hexane or diethyl ether into solutions
of the complexes in acetone or CH2Cl2. Single-crystal X-ray dif-
fraction studies were carried out with a BRUKER X8 APEX CCD
diffractometer at room temperature by using graphite-monochro-
mated Mo-Kα radiation (λ = 0.71073 Å). The absorption was cor-
rected with the SADABS program.[14] All structures were solved by
means of direct methods and refined by full-matrix least-squares
techniques with the SHELXTL program.[14] Hydrogen atoms were
calculated to their idealized positions and were refined as riding
atoms. Selected distances are shown in Tables 1 and 2. Polycrystal-
line samples were studied in the 2θ range 5–120° with a DRON
RM4 powder diffractometer equipped with a Cu-Kα source (λ =
1.5418 Å) and graphite monochromator at the diffracted beam. In-
dexing of the diffraction patterns was carried out using data for
pure metals and compounds reported in the JCPDS-ICDD datab-
ase.[15] Unit cell parameters were refined by the full-profile tech-
nique within the whole diffraction range with the POWDERCELL
2.4 program.[16] Crystallite sizes of the prepared bimetallic powders
were determined by Fourier analysis of single diffraction peaks (the
program WINFIT 1.2.1[17]).

Electron Microscopy: HRTEM (high resolution transmission elec-
tron microscopy) micrographs were obtained with a JEM-2010
(JEOL, Japan) instrument with a lattice resolution of 0.14 nm and
accelerating voltage of 200 kV. The samples for the TEM study
were prepared by ultrasonic dispersing in ethanol and consequent
deposition of the suspension upon a “holey” carbon film supported
on a copper grid. Local elemental analysis was performed with the
EDX method with an Energy-dispersive X-ray Phoenix Spectrome-
ter equipped with a Si (Li) detector with an energy resolution not
worse than 130 eV.
