Novel compounds, (3,6-dichloro-2-nitrophenyl)(3-nitrophenyl)methanone(2), (2-amino-3,6-dichloro- phenyl)(3-aminophenyl)methanone(3) and 1-[3-(2-amino-3,6-dichlorobenzoyl)phenyl]-1H-pyrrole-2,5-dione(4), were synthesized from the initial compound 2,5-dichiorobenzophenone(1) and characterized by <'1>H NMR, <'13>C NMR, IR, mass spectrum and element analysis, respectively. The single crystal of compound 2 was obtained and determined by X-ray diffraction analysis. The single crystal data illustrates that it belongs to the monoclinic system, space group P2<,1>/c with a=0.7587(4) nm, b=2.4724(4) nm, c=0.8081(3) nm, α=90°, β=112.85(2)°, y=90°, V=1.3970(9) nm<'3>, Z=4, D<,c>=1.622 g/cm<'3>, M<,r>(C<,13>H<,6>Cl<,2>N<,2>O<,5>)=341.10,/μ(Mo Kα)=0.49 mm<'-1>, F(000)=688, the final R=0.048 and wR=0.144 for 1665 observed reflections with l>2σ(Ⅰ). The title molecule forms a "T" type crystal structure and the dihedral an- gel of the two phenyl rings is 65.0(1)°.

小秦岭中矿带金矿田成矿构造分析

小秦岭金矿田中矿带是在老鸦岔背形翼部韧—脆性剪切带的基础上由含矿流体贯入形成的含金石英脉,其不仅延伸较长、延深较大,而且矿脉较宽,展布有文峪、东闯、杨寨峪、长安岔和金硐岔等大中型金矿。在概述成矿地质背景、归纳矿脉地质特征的基础上,分析了该区成矿地质作用,认为成矿流体主要来自深源,通过地幔热柱多级演化,贯入到早期韧—脆性剪切带中积聚结晶,形成一条或多条规模较大的含金石英脉,甚至出现研究区主矿脉所占有的金属储量超过矿区50%～90%的金属储量的现象。在今后的工作中,建议不要依据矿权的划分来评价矿床规模,而应根据矿脉的自然展布来统筹评价矿床规模,包括指导矿区深部和外围勘查工作。
