The compositions of complexes were determined as, by chemical and elemental analyses, Mn2CI2, Mn2Cl2, Cu2Cl2-2H2O, Cu(NO3)2-H2O, Cu(CH3COO)2, Zn2Cl2, Zn2(NO3)2-4H2O,ZnSO4 and Zn4(NO3)2, respectively. These complexes were characterized by IR,'H NMR and XPS. The crystal structures of these complexes were determined by single crystal X-ray diffraction techniques. The thermstability of the complexes was investigated by TG-DTG and the processes of their thermal decomposition were speculated. The constant-volume combustion energies of complexes, cU, were determined by a precision rotating bomb calorimeter at 298.15 K. Their standard enthalpies of formation, Hm, were calculated respectively. Finally, their biological activity was researched after the bactericidal activity was determined by selection of 1-2 bacteria.

Such features are typical of ancient lower continental crust, e.g., Archean granulite terranes that experienced extensive U-Th loss and developed time-integrated low radiogenic Pb compositions. The occurrence of the west Ujimqin andesites indicates the existence of ancient continental lower crust beneath the NE China fold belt.4 The Mesozoic granitoids in the Zhangguangcai Range and Jiamusi block have lower Nd ε_(Nd =-3.5~+ 2.1, T_ = 1.0~1.27Ga and highly radiogenic Pb and Sr isotopic composition ~(206Pb/~(204)Pb = 18.4~18.9,~(87)Sr/~(86)Sr = 0.705~0.711, suggesting that the pelagic sediments of the Paleo-Asian Ocean or their metamorphosed derivates were an important component in the region.5 The Pb isotope mapping results show that the mafic rocks in the northern Hinggan Mountains have higher and weakly variable ~(206)Pb/~(204)Pb ratios than those from the southern Hinggan Mountains and the Liaoyuan-Yanji area.
该套岩石的出现为证明东北地区存在古老大陆下地壳提供了重要证据。4张广才岭-佳木斯地区中生代花岗岩表现出低ε_(-3.5~+2.1)、高T_(1.0~1.27Ga)和高放射成因Sr~(87Sr/~(86)Sr=0.705~0.711和Pb同位素组成~(206Pb/~(204)Pb=18.4~18.9,反映了古亚洲洋远洋沉积物或变沉积岩为区域地壳的重要组分之一。5同位素填图结果表明,大兴安岭北区基性火山岩表现出较高且变化小的~(206)Pb/~(204)Pb比值;而南兴安岭-辽源-延吉地区中生代基性火山岩整体上表现出相对北区低~(206)Pb/~(204)Pb同位素比值特征。
