N2 - Two new compounds, [Ho 26(IN) 28(CH 3COO) 4(CO 3) 10(OH) 26(H 2O) 18]20H 2O (1) (HIN=isonicotinic acid) and [Er 26(IN) 29(CH 3COO) 3(CO 3) 10(OH) 26(H 2O) 19] 26H 2O (2), employing the building unit of CO 3@Ln 26 have been synthesized hydrothermally. Compound 1 crystallizes in the triclinic space group with a=21.043(4)Å, b=21.128(5)Å, c=35.140(8)Å, α=85.838(3)°, β=74.909(3)°, γ=85.414(3)°, V=15,014(6)Å 3, Z=2; 2 crystallizes in triclinic with a=20.9968(15)Å, b=21.1260(15)Å, c=35.125(3)Å, α=85.9530(10)°, β=74.7590(10)°, γ=85.5020(10)°, V=14,966.3(18)Å 3, Z=2. In the structures of both compounds, the isonicotinate (IN) is the main ligand while CH 3COO - functions as the second ligand to stabilize the Ln 26 cluster; plays a very important role in the formation of the spherical Ln 26 cluster. The two compounds are isostructural and have been characterized by single-crystal X-ray diffraction, IR absorption spectroscopy, thermogravimetric analysis, ultraviolet excitation, and emission spectrum.
