Compound 4 can also be synthesized by reacting6-amino-3(2H)mercapto-1,2,4-triazolo[3,4-f][1,2,4]triazin-8(7H)-one (7) with benzylbromide in methanolic ammonia water. The compound crystallizes in the monoclinicspace group P21\/c with a = 7.2926(15), b = 14.456(2), c = 11.436(2) \u00e5, \u03b2 = 105.30(2)\u00b0, V= 1162.9(4) \u00e53 and Z = 4, resulting in a density Dcalc of 1.567 g\/cm3. Molecules of 4 arelinked by extensive intermolecular N-H\u00b7\u00b7\u00b7N and N-H\u00b7\u00b7\u00b7O hydrogen bonding [graph set R22 (9)]. The structure is further stabilized by \u03c0-\u03c0 stacking interactions. 2<\/jats:p>","DOI":"10.3390\/11020169","type":"journal-article","created":{"date-parts":[[2008,10,25]],"date-time":"2008-10-25T13:32:11Z","timestamp":1224941531000},"page":"169-176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Synthesis and Molecular Structure of 6-Amino-3-benzylmercapto-1,2,4-triazolo[3,4-f][1,2,4]triazin-8(7H)-one"],"prefix":"10.3390","volume":"11","author":[{"given":"Long-Chih","family":"Hwang","sequence":"first","affiliation":[{"name":"Faculty of Medicinal and Applied Chemistry, Kaohsiung Medical University, Kaohsiung City 80708, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Hsie","family":"Tu","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Longcyuan Veterans Hospital, Pingtung 912, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung-Hui","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Pharmacy, Kaohsiung Veterans General Hospital, Kaohsiung City 807, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gene-Hsiang","family":"Lee","sequence":"additional","affiliation":[{"name":"nstrumentation Center, College of Science, National Taiwan University, Taipei City 106, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2006,3,17]]},"reference":[{"key":"ref_1","unstructured":"Weissberger, A., and Taylor, E.
