摘要

本文报道了三个异金属环[Pr2NH2][(Pr2NH2)Cr6IIIM2IIF8(BTFB)16] (M为Ni、Co或Zn, BTFBH = 3,5-二(三氟甲基)苯甲酸),它们是用二正丙基铵阳离子模板化的。该环在一个八角形的四角上含有6个Cr(III)离子和2个M(II)离子,二价金属离子在环周围无序分布。八边形的每条边都由一个氟化物和两个桥接的BTFB-配体桥接。晶体结构中的两个铵离子,一个位于八角形环的中心,另一个位于环外。环中的两种二价金属导致异构体的存在,这可以在MII = Ni或Zn的磁性和EPR研究中看到,以及MII = Co的19F-NMR光谱中看到。数据被解释为大约50:50的异构体混合物,其中二价离子位于环中的1,5和1,2位置。进行了不同的反应,得到[(Pr2NH2)][Cr7IIIMIIF8(BTFB)16]环;它们不能用晶体学完全表征,但它们的形成可以通过元素分析、质谱分析、核磁共振光谱(对于M = Co)、磁性研究和EPR光谱(对于M = Ni, Zn)来证实。

Unexpected Family of Heterometallic Rings {Cr6M2} with 3,5-Bis(trifluoromethyl)benzoate

Unexpected Family of Heterometallic Rings {Cr6M2} with 3,5-Bis(trifluoromethyl)benzoate

Three heterometallic rings, [Pr2NH2][(Pr2NH2)Cr6IIIM2IIF8(BTFB)16] (M is Ni, Co, or Zn, BTFBH = 3,5-bis(trifluoromethyl)benzoic acid) are reported, templated about a di-n-propylammonium cation. The ring contains six Cr(III) ions and two M(II) ions at the corners of an octagon, with the divalent metal ions disordered around the ring. Each edge of the octagon is bridged by a fluoride and two bridging BTFB ligands. One of the two ammonium cations in the crystal structure is located at the center of the octagonal ring, and the other outside the ring. Two divalent metals in the ring lead to the presence of isomers, which can be seen in the magnetic and EPR studies for MII = Ni or Zn, and 19F-NMR spectra for MII = Co. The data are interpreted as resulting from an approximately 50:50 mixture of isomers, where the divalent ions are at the 1,5 and 1,2 positions in the ring. A different reaction was pursued, which gave [(Pr2NH2)][Cr7IIIMIIF8(BTFB)16] rings; these could not be fully characterized by crystallography but their formation is confirmed by elemental analysis, mass spectrometry, NMR spectroscopy (for M = Co), magnetic studies, and EPR spectroscopy (for M = Ni, Zn).

期刊介绍: Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
