四（正丁基）铵由双核新戊酸钌（II，III）组成的Ru 2-W络合物的（n-Bu 4 N+）盐，（[Ru III（piv）4]+）（HPIV=特戊酸）和八氰基钨酸盐（V）[n-Bu 4 N][{Ru II Ru III（piv）4} 2（H2 O）{W V（CN）8}]（1）的合成，以及磁化率的温度依赖性（2-300 K）。1的晶体结构显示出一个沿c轴沿着的锯齿形一维链状分子，[Ru II Ru III（piv）4]+和[W V（CN）8] 3-交替排列，其中另一个[Ru II Ru III（piv）4]+单元悬挂在[W V（CN）8] 3-部分上。磁化率、零场冷却和场冷却磁化强度数据表明，配合物为亚铁磁性配合物，Tc值为5.5K。磁化强度的场依赖性表现出磁滞现象，在2K时矫顽场为150 Oe。
A tetra (n-butyl) ammonium (n-Bu 4 N+) salt of Ru 2–W complex consisting of dinuclear ruthenium (II, III) pivalate,([Ru II Ru III (piv) 4]+)(Hpiv= pivalic acid), and octacyanidotungstate (V),[n-Bu 4 N][{Ru II Ru III (piv) 4} 2 (H 2 O){W V (CN) 8}](1), was synthesized and characterized by elemental analysis, infrared spectra, and temperature dependence of magnetic susceptibilities (2–300 K). The crystal structure of 1 revealed a zigzag one-dimensional chain molecule along the c axis with alternating arrangement of [Ru II Ru III (piv) 4]+ and [W V (CN) 8] 3−, where another [Ru II Ru III (piv) 4]+ unit is dangled from the [W V (CN) 8] 3− moiety. The magnetic susceptibilities and zero-field-cooled and field-cooled magnetization data showed that the present complex is ferrimagnetic with a T c value of 5.5 K. The field dependence of magnetization exhibited a hysteresis with a coercive field of 150 Oe at 2 K.
