In the title compound, C(15)H(10)BrClO, the dihedral angle between the mean planes of the benzene rings in the ortho-bromo- and para-chloro-substituted rings is 70.5 (6)°. The dihedral angles between the mean plane of the prop-2-en-1-one group and the mean planes of the benzene rings in the 4-chloro-phenyl and 2-bromo-phenyl rings are 14.9 (3) and 63.3 (8)°, respectively. In the crystal, invers...

The title compound 6-amino-3-benzylmercapto-1,2,4-triazolo[3,4-f][1,2,4]-triazin-8(7H)-one (4), molecular formula C(11)H(10)N(6)OS, was obtained by the reaction of 3-amino-2-benzyl-6-hydrazino-1,2,4-triazin-5(2H)-one (3) with carbon disulfide in a water/pyridine mixture. Compound 4 can also be synthesized by reacting 6-amino-3(2H)mercapto-1,2,4-triazolo[3,4-f][1,2,4]triazin-8(7H)-one (7) with b...

A new zinc compound, together with a corresponding series of Zn-4f heterometallic coordination polymers, namely, [Zn(H2PBDA)(PBDA)]n (1), {[Ln2(PBDA)2·2H2O] [Zn2(PBDA)2Cl2]}n [H2PBDA = 3-(pyridin-3-yl-oxy) benzene-1,2-dicarboxylic acid, and Ln = Pr(2), Nd(3), Eu(4), Gd(5), Dy(6), Ho(7), Er(8)] have been hydrothermally synthesized and characterized systematically. Polymers 2-8 feature two-dimens...

The title complex, {[Mn(C(14)H(8)O(4)S(2))(C(12)H(8)N(2))(2)]·0.5CH(3)OH·H(2)O}(n), has a one-dimensional chain structure in which the Mn(II) atom is six-coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and two O atoms from two 2,2'-dithio-dibenzoate (L) ligands. The L ligands adopt a bis-(monodentate) (syn-anti) coordination mode and bridge adjacent Mn(II) centres, gener...
