【Abstract】 A novel supramolecular complex,[Co（L-alanato）₂（phen）]NO₃·4H₂O（1）,was synthesized by the hydrothermal reaction of Co（NO₃）₂·6H₂O with L-alanine and 1,10-phenanthroline（phen）.The structure was characterized by IR,elemental analysis and single crystal X-ray diffraction analysis.1 belongs to triclinic system,space group P-1 with a=10.121 9（5） ,b=11.461 1（12） ,c=12.573 2（12） ,α=71.13（3）°,β=67.52（3）°,γ=66.08（3）°,V=1207.24（18） 3,Dc=1.511 g·cm-3,Z=2,F（000）=572,Mr=549.38,μ=0.777 mm-1,R₁=0.083 6,ωR₂=0.214 2.1 exhibited a metabolic octahedral structure by a six-coordinated of central atom Co（Ⅲ） with one phen and two alanine ligands.Intermolecular hydrogen bond of 1 constituted three-dimensional structure.The results from thermal analysis showed that 1 in turn lost crystal water and 1,10-phenanthroline during heating.更多还原
