This paper reports four homochiral zinc phosphonates, alpha-(S)-[Zn 2(pemp)(pempH)Cl] (1), alpha-(R)-[Zn 2(pemp)(pempH)Cl] (2), beta-(S)-[Zn 2(pemp)(pempH)Cl] (3), and beta-(R)-[Zn 2(pemp)(pempH)Cl] (4) [pempH 2 = (1-phenylethyl)amino]methylphosphonic acid]. Both 1 and 2 are enantiomers, crystallizing in an orthorhombic P2(1)2(1)2(1) space group, while 3 and 4 are polymorphic phases of 1 and 2, respectively, crystallizing in a monoclinic P2(1) space group. The polymorphism is induced by temperature or additional organic molecules.
本文报道了四种同手性的锌膦酸盐,α-(S)-[Zn₂(pemp)(pempH)Cl] (1)、α-(R)-[Zn₂(pemp)(pempH)Cl] (2)、β-(S)-[Zn₂(pemp)(pempH)Cl] (3) 和 β-(R)-[Zn₂(pemp)(pempH)Cl] (4) [pempH₂ = (1-苯乙基)氨基甲基膦酸]。1 和 2 是对映体,结晶于正交晶系 P2(1)2(1)2(1) 空间群,而 3 和 4 分别是 1 和 2 的多晶型相,结晶于单斜晶系 P2(1) 空间群。这种多晶型现象是由温度或额外的有机分子诱导产生的。
