摘　　要：Treatment of resorcin[4]arene tetracarboxylic acid 1 with triethylamine in the presence of Co（CH3COO）2·4H2O and 4,4 -bipyridine gave a co-crystallization 14-·4Et3NH＋（C32H20O164-·4Et3NH＋,Mr=1069.27） from ethanol and water.The compound was structurally determined by single-crystal X-ray diffraction.The crystal belongs to monoclinic,space group P21/n,with a=8.1763（18）,b=12.913（3）,c=28.724（7） ,β=97.574（4）o,V=3006.3（12） 3,Z=2,Dc=1.181 g/cm3,F（000）=1152,Rint=0.0275,T=293（2） K,μ=0.086 mm-1,the final R=0.0634 and wR = 0.1752 for 5082 observed reflections with I 〉 2σ（I）. The co-crystallization is very stable at room temperature. Possibly, a network of N-H…O（=C） plays an important role in the structure. Meanwhile, the compound emits a weak cyan luminescence with peak maximum band at 458 nm.Treatment of resorcin[4]arene tetracarboxylic acid 1 with triethylamine in the presence of Co（CH3COO）2·4H2O and 4,4 -bipyridine gave a co-crystallization 14-·4Et3NH＋（C32H20O164-·4Et3NH＋,Mr=1069.27） from ethanol and water.The compound was structurally determined by single-crystal X-ray diffraction.The crystal belongs to monoclinic,space group P21/n,with a=8.1763（18）,b=12.913（3）,c=28.724（7） ,β=97.574（4）o,V=3006.3（12） 3,Z=2,Dc=1.181 g/cm3,F（000）=1152,Rint=0.0275,T=293（2） K,μ=0.086 mm-1,the final R=0.0634 and wR = 0.1752 for 5082 observed reflections with I 〉 2σ（I）.
