STUDY ON SYNTHESIS,CHARACTERIZATION AND STRUCTURE OF A NEW RARE EARTH COORDINATION COMPOUND WITH BENZOIC ACID

In this paper,a new rare earth benzoate coordination compound,[TbL_3(HL)(H_2O)]_2 (HL=C_7H_6O_2=benzoic acid) is synthesized and characterized by elemental analysis DTA,TG,DTC,and IR spectra.The title compound crystallizes in triclinic,space.group P with a=9.148(1),b=11.460(2), c=13.506(2);α=112.76(1),β=91.83(1),γ=91.99(1)°;Z=1;V=1303.3.The final R factor is 0.0235.The rare earth ion is nine-coordinated to form a distorted monocapped square antiprism.

Exploration on the Characteristics and Important Relationships of Xi Jinping's New Concept of Coordinated Economic Development

During the 18 th CPC National Congress, Xi Jinping raised a series of economic development thoughts, namely the five new concepts of development; innovative, coordinated, green, open and shared development, and put forward a series of economic development thoughts including"people-centered"economic development. These are the new summations of the practice of socialism with Chinese characteristics, and the latest achievements in the theory of the political economics of socialism with Chinese characteristics."People-centered"is both the starting point and final purpose of coordinated economic development, an accurate mastery of social and economic development rules, and also the foundation and specific manifestation of coordinated development between people and society. People's subjectivity, coordinated inclusiveness and dialectics of development are the characteristics of coordinated economic development. Regional coordinated development, urbanrural coordinated development, industrial coordinated development, coordinated development of national defense and economic construction, supply and demand coordinated development, ecological coordinated development and interacted coordinated development of the global economy are the important relationships of coordinated economic development that we have to recognize and handle properly.
