摘要：
Two cobalt complexes [NaCoII(nta)(H2O)(])n (H(3)nta nitrilotriacetic acid) (1) and NH4[Co-III(ida)(2)] center dot 2H(2)O (H(2)ida iminodiacetic acid) (2) have been synthesized and characterized by single-crystal X-ray diffraction analysis. Compound 1 crystallizes in the orthorhombic system, space group P2(1)2(1)2(1) with a=7.9770(12) angstrom, b=9.7613(15) angstrom, c=12.1945(18) angstrom, V=949.5(2) angstrom(3), Z=4, and R-1 0.0705 for 1597 observed reflections. Compound 2 crystallizes in the monoclinic system, space group P2(1)/c with a=5.1801(3) angstrom, b=11.2073(6) angstrom, c=12.2891(7) angstrom, V=707.09(7) angstrom(3), Z=2, and R-1=0.0349 for 1143 observed reflections. In compound 1, the Co is coordinated by a nitrogen and five oxygen atoms in a distorted octahedral geometry {CoNO5}, and the Na is coordinated by one water molecule and four carboxyl oxygen atoms in slightly distorted square pyramidal geometry. The entire structure shows a three-dimensional network. In compound 2, Co atom is equatorially coordinated by two ida ligands in a distorted octahedral geometry {CoN2O4}. The discrete [Co(ida)(2)](2-) anions are linked by hydrogen bonding to a three-dimensional supramolecular network.
