英语翻译
One new coordination polymer [Mn(dpa)(IP)]n (H2dpa=3,4’-Biphenyl-dicarboxylic acid and IP=imidazo[4,5-f][1,10]phenanthroline) was synthesized by hydrothermal reaction and was characterized by single-crystal X-ray .Complex [Mn(dpa)(IP)]n is a one-dimensional chain which is bridged by dpa2- ligands.

通过水热反应合成了一种新的配位聚合物[Mn(dpa)(IP)]n (H2dpa=3,4'-联苯二甲酸,IP=咪唑并[4,5-f]邻菲咯啉）,并用单晶X射线进行表征.化合物 [Mn(dpa)(IP)]n是dpa2-配体桥接而成的一维链状结构.
结构里面写的dpa就应该是最后一句里面写的dpa2-离子,就是3,4'-联苯二甲酸去掉两个羧基上氢离子

已知m-n=4,mn=2,求多项式（-2mn+2m+3n)-(3mn+2n-2n)-(m+4n+mn)的值已知m-n=3,mn=-3,求(-m-4n-mn)-(2mn-2m-3n)-(3mn+2n-2m)的值已知m-n=4,mn=2,求多项式（-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)的值. 若m-n=4,mn=-1求(9-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn) 若m-n=4,mn=-1,求(-2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)的值若m-n=4,mn=-1,求(-2mn+m+n)-(3mn+5n-5m)-(m+4n-3mn)的值已知m-n=3,mn=-1,求多项式-2mn+2m+3n-3mn-2n+2m-4n-m-mn的值已知m-n=2,mn=1,求多项式(2mn+2m+3n)-(3mn+2n-2m)-(m+4n+mn)的值已知m+n=2 mn=-4,则2（mn-3m）-3(2n-mn) m+n=-2 mn=-4则2(mn-3m)-3(2n-mn)的值为已知m+n=-2,mn=4,求2(mn-3m)-3(2n-mn)的值. 知m*m-mn=1,4mn-3n*n=-2,则m*m+3mn-3n*n的值是多少
