摘　　要：2,2'-联吡啶胺(1)的结构经单晶X-射线衍射测定,化合物1的结晶是以正交空间群Pccn,其晶胞参数为a=12.3184(10)A觷,b=18.4042(15)A觷,c=7.7551(7)A觷;和Z=8,化合物1通过一个对称中心形成氢键二聚体。1的钯配合物[PdCl2(2-py)2NH](2)是以单斜空间群P21/n结晶,其晶胞参数为a=10.2510(6)A觷,b=9.5094(6)A觷,c=12.2696(7)A觷;β=97.8650(1)°;和Z=4,化合物2的结构含有一个微扭曲四平面构型的钯中心键合2,2'-联吡啶胺的两个氮原子和两个氯原子,平均Pd-N和Pd-Cl的键长分别是2.022(2)and2.3140(7)A觷。The crystal structure of 2,2'-bipyridylamine (1) was determined by single-crystal X-ray diffraction. Crystallization of 1 occurs in the orthorhombic space group Pccn with a=12.318 4(10)?,b=18.404 2(15)?,c= 7.755 1 (7)?; and Z=8. Compound 1 forms hydrogen-bonded dimers across an inversion center. The palladium complex of 1, ^PdCl2(2-py)2NH^ (2), crystallizes in the monoclinic space group P21/n with a=10.251 0(6)?, b=9.509 4(6)?,c= 12.269 6(7)?;β=97.865 0(1)°; and Z=4. The structure of 2 consists of a slightly distorted square planar conformation of the palladium center, bonding two nitrogen atoms in 2,2'-bipyridylamine and two chloride atoms. The average Pd-N and Pd-Cl bond lengths are 2.022(2) and 2.314 0(7) ? respectively.
