C 26 H 42 N4O15Ni, triclinic, P¯ (no. 2), a = 6.9662(8) Å, b = 9.0381(10) Å, c = 13.4863(15) Å, CCDC no.: 1470488Only the asymmetric unit is shown in the gure. Tables 1-3 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialThe mixture of Ni(OAc) 2 . 4H 2 O (0.050 g, 0.2 mmol) and H 3 minca (2-(hydroxyl)-6-methyl-isonicotinic acid, 0.039 g,

In order to improve the recovery of braking energy in electric vehicles, a braking force distribution control strategy is proposed which the braking force proportion of the front and rear wheels are distributed according to the brake strength, by analyzing the vehicle braking mechanics and related braking regulation, and combining with the motor output characteristics. A simulation is carried out with SIMULINK/ADVISOR, the results show that, comparing with ADVISOR braking force distribution control strategy, the control strategy not only meets braking stability well，but also there are obvious advantages in energy consumption per 100 kilometers，the rate of braking energy recovery and utilization.

C 13 H 14 N 2 O 6 , monoclinic, P2 1 /c (no. 14), a = 3.829(1) Å, Source of materialThe mixture of 4-hydroxylpyridin (0.021 g, 0.2 mmol) and 5-bromobenzene-1,3-dioic acid (0.043 g, 0.2 mmol), was stirred in 15 mL ethanol. Then the pH value was adjusted to approx. 5.5 with 1.0 mol/L nitric acid. After stirring for 10 min in air the mixture was placed into a 25 mL Teflon-lined stainless steel autoclave under autogenous pressure, and heated at 65°C for 36 h. The autoclave was cooled over a period of 12 h at a rate of 5°C/h.
