Two new Zn~Ⅱ coordination polymers [Zn(oba)(4,4?-bipy)]n(1) and [Zn(oba)-(bpe)_(1/2)(H_2O)]_n(2)(H_2oba = 2,2?-oxybis(benzoic acid), 4,4?-bipy = 4,4?-bipyridine, bpe = 1,2-bis(4-pyridyl)ethylene) were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, IR spectroscopy and elemental analysis. Complex 1 shows a 3D metal-organic framework with a uninodal 4-connected 65.8 dmp network. Complex 2 features 1D ladder-shaped chains, which are further connected into a 2D stair-step network through intermolecular O–H···O hydrogen bonds.

传统的羊膜腔穿刺和绒毛吸取是目前许多医院较为常用的产前诊断技术,因其操作易导致流产、胎儿损伤或死亡、宫内感染、羊膜破裂等,使其在临床上的推广和应用受到了限制.利用孕妇外周血中的胎儿细胞进行遗传学诊断一直是无创性产前诊断的重要探索途径[1].但由于孕妇外周血中的胎儿细胞数量少,而且存在个体差异,目前很难从外周血中分离出完整的胎儿细胞,这无疑限制了这种方法在临床上的应用[2].1997年,有学者研究发
