Abstract

The reaction of adduct Cu2(OOCBut)4(thf)2 with polynuclear nickel(II) pivalate (prepared from NiCl2, HOOCBut, and KOH) or cobalt(II) pivalate (prepared by thermolysis of Co(II) acetate with excess acid at 160°C) in THF with a large excess of aqueous ammonia at room temperature leads to the formation of the mononuclear molecular complex Cu(OOCBut)2(NH3)2, the ionic complex [Ni(NH3)6](OOCBut)2, and unusual mixed-valence trinuclear complex {CoII(OOCBut)2(NH3)2[(µ-OH)CoIII(NH3)5]2}(OOCBut)4(H2O)2. The products were investigated by chemical analysis, X-ray diffraction, and IR spectroscopy.

摘要

加合物 Cu 2 (OOCBu t ) 4 (thf) 2与多核新戊酸镍 (II)(由 NiCl 2、HOOCBu t和 KOH 制备)或新戊酸钴(II)(由乙酸钴(II)热解制备)的反应在 160°C 下用过量的酸在 THF 中用大量过量的氨水在室温下形成单核分子络合物 Cu(OOCBu t ) 2 (NH 3 ) 2,离子络合物 [Ni(NH 3 ) 6 ](OOCBu t ) 2,和不寻常的混合价三核络合物{Co II (OOCBut ) 2 (NH 3 ) 2 [(μ-OH)Co III (NH 3 ) 5 ] 2 }(OOCBu t ) 4 (H 2 O) 2。通过化学分析、X 射线衍射和红外光谱对产物进行了研究。
