โฆ Synopsis
Two new compounds have been synthesized and characterized: ZrP 2 S 6 and ZrP 2 S 7 . Both were prepared from direct combination of the elements at high temperature using a chemical transporting agent. Single crystal X-ray diffraction and elemental analysis (ICP-AE) were performed on the materials. ZrP 2 S 6 crystallized in a tetragonal space group (P-4, a โซุโฌ 6.6758(4) A s , c โซุโฌ 9.491(1) A s ) whereas the ZrP 2 S 7 crystallized in a monoclinic space group (C2/c, a โซุโฌ 8.614(1) A s , b โซุโฌ 29.684(4) A s , c โซุโฌ 8.583(1) A s , โซุโฌ 120.126ยฐยฐ). The ZrP 2 S 6 displayed a weak second harmonic generation at 1064 nm. 1999 Academic Press
