Syntheses, Crystal Structures and Properties of Two New Compounds from a Flexible Bipodal Acid with Additional Amide Groups

摘要

Two novel compounds { [Cu(IBG)(4,4'-bipy)(H2O)2]2· 11H2O}n (1) and { [Co(IBG)-(u-H2O)(H2O)2]·2H2O}n (2) based on isophthaloylbisglycine (H2IBG) have been synthesized and structurally characterized by thermogravimetric analysis,elemental analysis and single-crystal X-ray diffraction.Compound 1 shows a 1D chain sine/cosine chain structure,and compound 2 can be characterized as a 4-connected sql tetragonal planar network with the point symbol of {44·62}.Compound 2 has been characterized by magnetic measurements.In addition,1 and 2 display an interesting reversible crystal-to-amorphous transformation.
