	ion r1	ion r2
Gd2(BDC)3(H2O)4[a]	35.8	55.6
Gd2(BDC)3(H2O)4[b]	26.9	49.1
Gd2(BDC)3(H2O)4[c]	20.1	45.7
[Gd(iBTC)(H2O)3]·H2O	13.0	29.4
Gd2(BHC)(H2O)6	1.5[d]	122.6[d]
Mn(BDC)(H2O)2	5.5	7.8

All relaxivities were obtained at 3.0 Tesla and are given in mM⁻¹ s⁻¹.

^[a]Nanoparticle size was ~100 × 40 nm.

^[b]Nanoparticle size was ~400 × 70 nm.

^[c]Nanoparticle size was ~1000 × 100 nm.

^[d]Values obtained at 9.4 Tesla.
