Аннотация

Single crystal X-ray diffraction at a temperature of 150(2) K is used to determine the structures of two magnesium complexes with trifluoroacetylacetone: [Mg(tfac)2]3I and [Mg(H2O)2(tfac)2]·H2O II. Crystallographic data for I: space group P21/n, a = 12.5226(10) Å, b = 13.0591(7) Å, c = 12.6034(13) Å, β = 95.243(2)°, V = 2052.5(3) Å3, Z = 2; for II: space group P21/c, a = 10.826(2) Å, b = 7.0742(13) Å, c = 21.858(4) Å, β = 102.712(5)°, V = 1632.9(5) Å3, Z = 4. The isle structure of I is formed by linear trimeric molecules; in the structure of II the molecules of the complex and crystallization water form a layered framework using hydrogen bondings; the coordinated water molecules are in a trans position. The magnesium atoms have a distorted octahedral coordination environment, the Mg–O distances are 1.991(4)- 2.146(4) Å and 2.040(5)-2.073(5) Å in molecules of I and II respectively.
