    • 1 was synthesized in ∼80% yield via 1.5:1 Ni(NO 3)2 (139.9 mg)/K3[Ru2(CO 3)4]·4H2O (200.6 mg) each dissolved in 20 mL of H2O. The anion was added to the stirring solution of Ni II at the rate of 19.8 mL/h using a syringe pump. The initial black precipitate was removed via centrifugation, and the desired product was precipitated with addition of MeOH, washed with MeOH, and dried in a vacuum desiccator with P2O5 overnight.

    • A Si(111) channel-cut monochromator selected a highly collimated incident beam of 0.69667(1) Å on the X16C beamline at National Synchrotron Light Source, BNL. The diffracted X-rays were analyzed by a Ge(111) single-reflection crystal and detected using NaI scintillation counter. The capillary was rotated during data collection for better averaging of the data. TOPAS-Academic was used to index, assign the space group, and solve the structure by the simulated annealing method and subsequent Rietveld refinement. Rigid-body constraints were imported to describe the D4h, Ru dimer, but interatomic distances were refined.

    • 4h, Ru dimer, but interatomic distances were refined. Solvent molecules necessary to explain the observed XRPD pattern were observed; we assumed water and oxygen atoms (O13-15); however, occupancy and thermal parameter are refined freely; consequently, atom identifications are not meaningful.
