A new screw shaped coordination compound for crystal engineering: Synthesis, crystal structure and nonlinear optical effect of o-chlorophenylthiourea zinc (II) diacetylacetonate
摘要:
This paper presents the synthesis and crystal structure of a new screw shaped square-pyramidal coordination compound, Zn(OCP-T)(acac)(2)(OCPT is o-chlorophenylthiourea). In the molecule, the "tail" length is almost equal to the width of the "head". The compound crystallizes in a noncentrosymmetric structure. The molecules are arranged in almost parallel direction. The compound showed the powder SHG (second harmonic generation) effect of about 1.5 times as large as that of KDP. (C) 2006 Elsevier B.V. All rights reserved.
