摘要
Two special manganese complexes [Mn（II）（acac ）2（4,4＇-bipy）]n （bipy=4,4＇-bipyridine） （complex 1） and [Mn（II1）（acac-）3].4CO（NH2）2 （acacH=acetylacetone） （complex 2） were synthesized in the same strategy by sol- vothermal method. Single crystal X-ray diffraction revealed the complex 1 consists of one-dimensional infinite coordination chain, with the manganese centers bridged by 4,4＇-bipy. And free carbamides of complex 2 connect with each other through the hydrogen bonds to form a 14-membered carbamide ring and a zig-zag plane. Both enantiomers of Mn（III）（acac ）3 exist in the structure, forming a racemate. Furthermore, these enantiomers and those zig-zag planes are linked with hydrogen bonds to form an unique spatial network.
