[Characteristics of nitrogen transportation in Castanea mollissima forest around the Fushi Reservoir watershed in north Zhejiang Province, China.].

In this study, through setting runoff plots in Chinese chestnut (Castanea mollissima) fo-rest, the runoff water samples were collected and tested from January to October, 2013. Combining with soil nitrogen data before and after the rainy season, we analyzed the characteristics of soil nitrogen transportation in chestnut forest around the Fushi Reservoir watershed in north Zhejiang Pro-vince, China. The results showed that among the 10 surface runoff events of Chinese chestnut fo-rest, there exhibited a significant difference in runoff water volume of each runoff plot, and the maximum amount was 0.

Poly[μ(2)-aqua-diaqua-(μ(8)-3-nitro-benzene-1,2-dicarboxylato)(μ(6)-3-nitro-benzene-1,2-dicarboxylato)tetra-sodium].

In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit μ(8)- and μ(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. One of the nitro groups is disordered over two sets of sites with site-occupancy factors 0.
