Abstract

Bis(hexafluoroacetylacetonato)diaquamanganese(II) [Mn(hfac)2(H2O)2] reacts with N-(4-pyridylmethy1)imidazole (pyim), trans-1,2-bis(4-pyridyl)ethylene (bpye) and imidazole (Him) to give their adducts with three different kinds of one-dimensional structures [Mn(hfac)2(pyim)] (1), [Mn(hfac)2(bpye)] (2) and [Mn(hfac)2(Him)2] (3), respectively. Compound 1 crystallizes in the monoclinic space group P21/n with a=9.696(3), b=14.839(4), c=17.076(3) Å, β=92.70(2)°, and assumes a one-dimensional structure running along the b-axis in which the adjacent molecules are related by a two-fold screw axis. Compound 2 crystallizes in the space group C2/c with a=9.554(2), b=16.476(2), c=16.137(2) Å, β=96.97(2)°, and assumes a zigzag-chain structure. Compound 3 crystallizes in the space group P21/c with a=7.526(3), b=14.506(3), c=10.394(2) Å, β = 96.71(2)° and the one-dimensional structure of 3 is formed by a hydrogen bond between NH of imidazole and O of hfac.
