Two-dimensional mixed-metal complexes composed of ruthenium(II,III) carboxylate (Ru2(RCOO)4+) and tetracyanidopalladate(II) (Pd(CN)42-) units, [{Ru2(RCOO)4}2Pd(CN)4] (R = CH3 (1), C2H5 (2), t-C4H9 (3)), were synthesized and characterized by elemental analysis, infrared and UV-vis-NIR spectra. Temperature-dependence of magnetic susceptibility (2-300 K) of (2) showed that a weak antiferromagnetic interaction through the Pd(CN)42- unit between the Ru2(C2H5COO)4+ units with zJ (the exchange integral multiplied by the number of interacting neighbors) = -0.1 cm-1 and D (zero-field splitting parameter) = 75 cm-1. The N2-adsorption isotherm measurement for (2) showed an adsorption property of Type II with an SBET value of 30.7 m2g-1.
