anticancer agents. Crystal structures of N-oxides contain planar molecules held together via hydrogen bonds involving oxygen atoms of N-oxide groups as acceptors. Crystal structure of 5 represents the first structure of a copper(II) complex with an N-oxide ligand derived from 8-HQNO and is formed by infinite chains. In the chain, the Cu(II) atom coordinates to six oxygen atoms from two bidentate chelating
四种 N-氧化物、8-羟基喹啉 N-氧化物 (8-HQNO)、5,7-二氯-8-羟基喹啉 N-氧化物 (HdClQNO)、5,7-二溴-8-羟基喹啉 N-氧化物 (HdBrQNO) 和 7 -iodo-8-quinolinol N-oxide (HIQNO) 及其六种铜配合物 CuCl 2 (8-HQNO) 2 (H 2 O) ( 1 )、CuCl 2 (HdClQNO) 2 (H 2 O) 2 ( 2 )、Cu(dClQNO) 2 (CHCl 3 ) ( 3 )、Cu(dClQNO) 2 (H 2 O) ( 4 )、[Cu(dBrQNO) 2 ]•2H 2 O} n ( 5 )和CuCl合成了2 (HIQNO) 2 (H 2 O) 4 ( 6 ) 作为可能的抗癌剂。N-氧化物的晶体结构包含通过氢键结合在一起的平面分子,包括作为受体的 N-氧化物基团的氧原子。5的晶体结构代表铜 (II)
