| 摘 要： | Using the ligand 4-sulfonyl-2,6-naphthalenedicarboxylate (SNDC), a coordination compound [Co(H2O)6]2[Co(SNDC)2(H2O)4]·4H2O(1) was synthesized and characterized by elemental analysis, thermal analysis, IR and single crystal X-ray diffraction structure analysis. The complex crystallizes in the triclinic P1 space group. The crystallographic data are: a=0.722 4(3) nm, b=1.181 2(4) nm, c=1.353 4(5) nm, V=1.039 47(7) nm3, Z=1, Dc=1.795 g·cm-3, R1=0.055 8, wR2=0.148 7. In the complex, the cobalt(Ⅱ) mononuclear anion ([Co(SNDC)2(H2O)4]4-) adopts the six-coordinated octahedral geometry furnished by two carboxylate oxygen atoms from the SNDC ligands and four water oxygen atoms. The cobalt(Ⅱ) mononuclear anions are self-assembled into two-dimensional sheets through hydrogen bonding between coordinated water molecules and carboxylate oxygens and π-π stacking of the aromatic naphthalene moieties. The [Co(H2O)6]2+ cations are intercalated between the layers through additional hydrogen bonds involving coordinated water molecules and sulfonate/carboxylate oxygen atoms. CCDC: 694556.
