Abstract
The reaction of the Mn2+ (aq) and [Cr(bipy)(C2O4)(2)](-) (aq) ions with 4,4 '-bipyridine-N,N'-dioxide leads to a heteropolymetallic system, [Mn(4,4'-bi pyridine-N,N'-dioxide) (H2O)(4)][Cr(bipy)(C2O4)(2)](2) . 8H(2)O (1) The cry stal structure of 1 consists of one-dimensional chains, (1)(infinity)[Mn(4, 4'-bipyridine-N,N'-dioxide) (H2O)(4)](n)(2n+), with Mn(II) ions bridged by 4,4'-bipyridine-N N'-dioxide ligands. The infinite homometallic chains are interconnected through hydrogen bonds with the water molecules and the [Cr( bipy)(C2O4)(2)](-) anions. The cryomagnetic measurements of compound 1 reve al weak anti-ferromagnetic interactions between the manganese(II) ions with in the chain (J= -1.2 cm(-1)). (C) 2001 Published by Elsevier Science B.V.
