采用热分解法合成了配位聚合物[Cu_5（piv）_5]_n（piv =特戊酸根）。该晶体结构的晶胞由一个右旋螺旋链和一个左旋螺旋链组成，它们是由Cu（I）离子和羧酸根（O-C-O）基团交替形成的。该链具有准5（3）螺旋轴;二级结构被认为是通过亲铜性和叔丁基的空间效应之间的平衡来实现的。
A coordination polymer, [Cu5(piv)5]n (piv = pivalate), was prepared by a thermal decomposition method. The unit cell of the crystal structure consisted of one right-handed helical chain and one left-handed helical chain, which were formed by an alternation of Cu(I) ions and carboxylate (O-C-O) groups. This chain possessed a pseudo-5(3) screw axis; the second-order structure was suggested to be realized by a balance between the cuprophilicity and a steric effect of the tert-butyl groups.
