A enneanuclear nanocage, [Ni9(HL)6(Pz)6](PzH)3(ClO4)3(H2O)24 (1), has been synthesized by coordination-driven face-directed self-assembly of octahedral Ni(II) ions and asymmetric hydrazone ligands with addition of pyrazole in ethanol solution. Compound 1 with hexahedral nanocage structure has been characterized by elemental analysis, FT-IR, TGA, ESI-MS, and X-ray diffraction analysis. Furthermore, variable-temperature magnetic studies for compound 1 have also been reported.
