Sažetak
A reaction of cobalt chloride hexahydrate with dimethoxyethane (dme) resulted in a dinuclear
complex [CoCl2(dme)]2 (1). The complex 1 reacted with di(2-methoxyethyl) ether (diglyme) in tetrahydrofuran
(thf) solvent achieving polymeric [Co2Cl4(diglyme)]n (2). A reaction of cobalt chloride hexahydrate,
diglyme and (CH3)3SiCl in thf yielded the crystals of [Co2Cl4(diglyme)(thf)] (3). Both, tetrahedral
and octahedral environments of cobalt ions were found in each of the complexes, 1, 2 and 3. Cobalt ions
display a distorted octahedral geometry with bridging chlorides and terminal oxygen atoms from ether
ligands and a distorted tetrahedral geometry with non-bridging and bridging chlorides. A four- and a sixcoordinate
cobalt ion are linked by a double chloride bridge in the dinuclear complexes 1 and 3. Two
tetrahedral or two octahedral cobalt ions in 2 are connected by double chloride bridges in dinuclear units
which are linked to infinite chains by single chloride bridges. (doi: 10.5562/cca1747)
