Abstract
Reactions of manganese and zinc chloride with dimethoxyethane (DME) in the presence of (CH 3) 3SiCl and water resulted in [MnCl 2(DME)] n ( 1) with a polymeric chain structure and in the molecular [ZnCl 2(DME)] 2 ( 2), respectively. The complexes 1 and 2 reacted with di(2-methoxyethyl) ether (abbreviated diglyme) in tetrahydrofuran (THF) solvent achieving binuclear [MnCl 2(diglyme)] 2 ( 3) and mononuclear [ZnCl 2(diglyme)] ( 4), respectively. The complex [NiCl 2(diglyme)] 2 ( 5) was prepared by the reaction of nickel chloride hexahydrate, diglyme and (CH 3) 3SiCl in THF solvent. A distorted octahedral geometry was found for manganese and nickel ions in the complexes 1, 3 and 5. Linear chains of manganese ions linked by double chloride bridges are present in 1. Two bridging chlorides connect two manganese or nickel atoms into isostructural binuclear molecules 3 and 5, respectively. Two zinc ions in the complex 2 are in different environments, in a tetrahedral and in an octahedral one, while five-coordinate zinc ions are present in the mononuclear complexes 4.
