X-ray distances for metal-(bi)carbonate complexes. Both mono- and bi-dentate coordination modes are included

r(Metal-13C) in carbonate modes (Cu-13C) Å (Co-13C) Å (Mn-13C) Å
Mono-dentate 2.9a 3.1b 3.35c
Bi-dentate 2.4-2.5a 2.3-2.4b 2.75-2.9c
2.75-2.95 (this work)
a

Based on X-ray diffraction on single crystals of copper complexes: [Cu(HCO3)](aq), [Cu(CO3)](aq), [Cu(CO3)2]2-(aq) and Na2[Cu(CO3)2](s)50

b

Based on X-ray diffraction on single crystal of cobalt complexes: K2[CoII(H2O)4(CO3)2](s) for mono-dentate, [CoIII(NH3)4CO3]Br(s) for bi-dentate48

c

Estimated based on ionic radii (Co3+ = 0.63 Å, Co2+ = 0.74 Å, Cu2+ = 0.69 Å and Mn2+ = 0.80 Å)
