The deuterated title compound, aqua adduct of ruthenium 3,4,5-tri(ethoxy-d5)benzoate, diaquatetrakis(μ-3,4,5-tri(ethoxy-d5)benzoato-O,O′)diruthenium(1+) tetrafluoroborate-tetrahydrofuran (1/1), [Ru2{3,4,5-(C2D5O)3CH2CO2}4(H2O)2]BF4·C4H8O, was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the monoclinic space group C2/c with a = 27.243(4)Å, b = 10.4850(15)Å, c = 23.115(3)Å, β = 100.789(3)°, V = 6486.1(16)Å3, Dx = 1.506 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0460 and 0.1037, respectively, for all 6597 independent reflections. The complex cation has a lantern-like dinuclear ruthenium core with axial water molecules [Ru-Ru 2.2629(8)Å].

The title compound, a chain adduct of rhodium(II) benzoate with 1,4-diazabicyclo[2.2.2]octane (dabco), catena(tetrakis(μ-benzoato-O,O′)(μ-1,4-diazabicyclo[2.2.2]octane-N,N′)dirhodium(II)-acetonitrile(1/4)), [Rh2(C6H5CO2)4(dabco)]n·4nCH3CN, was isolated. The crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. It crystallizes in the tetragonal space group P4/n with a = 21.3695(18)Å, c = 9.6278(12)Å, V = 4396.6(8)Å3, Dx = 1.468 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0417 and 0.0825, respectively, for all 5185 independent reflections. The molecule has a linear chain with an alternating arrangement of Rh2(C6H5CO2)4 [Rh-Rh 2.4062(11)Å, 2.4110(11)Å] and dabco. The adsorption property was confirmed for N2 gas with a specific surface area of 387.8 m2 g-1 estimated from an N2 adsorption isotherm.

The crystal structure of the fentanyl base (C22H28N2O) is monoclinic, P21/n. The unit-cell dimensions at 293 K are a = 5.69263(10)Å, b = 25.1851(5)Å, c = 13.8608(3)Å, β = 104.2037(7)°. The R value is R = 0.0626 for 2208 reflections. The piperidine ring has a near-ideal chair conformation. In the packing, the intermolecular T-shaped π/π interactions were observed.
