building block (FBB), namely, Co5[(C4H2O6)2B]2(H2O)6 (1), KCo2[(C4H2O6)2B](H2O)3 (2), and NH4Co2[(C4H2O6)2B](H2O)2·H2O (3), have been synthesized by hydrothermal method. Compound 1 crystallizes in the centric space group of P 1¯ and features a novel three-dimensional (3D) network, which is composed of 2D Co3[(C4H2O6)2B]2(H2O)2}2- anionic layers connected by Co(2)O6 octahedral. Compounds 2 and 3 both crystallize
制造新型硼酸盐非线性光学 (NLO) 材料的关键是构建 NLO 活性结构构件。本文介绍了三种基于新型 [B(C 4 H 2 O 6 ) 2 ] 5-基本结构单元 (FBB) 的新型酒石硼酸钴 (II),即 Co 5 [(C 4 H 2 O 6 ) 2 B] 2 ( H 2 O) 6 ( 1 ), KCo 2 [(C 4 H 2 O 6 ) 2 B](H 2 O) 3 (2 )和NH 4 Co 2 [(C 4 H 2 O 6 ) 2 B](H 2 O) 2 ·H 2 O ( 3 ),采用水热法合成。化合物1在P的中心空间群中结晶 1¯并具有新颖的三维 (3D) 网络,由 2D Co 3 [(C 4 H 2 O 6 ) 2 B] 2 (H 2 O) 2 } 2-阴离子层组成,通过 Co(2) 连接O 6八面体。化合物2和3均在P 2 1 2 1 2 1空间群中结晶。化合物2呈现 3D 结构,由
