Role of NEt4 in Orienting and Locking Together [M(2)lig(3)](2-) (6,3) Sheets (H(2)lig = Chloranilic or Fluoranilic Acid) to Generate Spacious Channels Perpendicular to the Sheets

Abstract

In the presence of the Et4N+ cation the chloranilate dianion (can2–) associates with a range of divalent cations, M2+, to yield an isomorphous series of crystalline compounds of composition (Et4N)2[M2(can)3] (M = Mg, Mn, Fe, Co, Ni, Cu, and Zn). The fluoranilate dianion (fan2–) likewise affords the closely related (Et4N)2[Zn2(fan)3]. The structures of (Et4N)2[Zn2(can)3], (Et4N)2[Fe2(can)3], and (Et4N)2[Zn2(fan)3] were determined by single crystal X-ray diffraction. Powder X-ray diffraction indicates that all the members of the can2– series are isomorphous. The structure of (Et4N)2[Zn2(fan)3] is very closely related to the structures of the can2– compounds. The [M2(can)32–]n component is pres..
