The crystal X-ray diffraction analysis shows that the crystal belongs to the triclinic with space group P1, M = 517. 23 and the unit cell parameters: a = 1. 4501 (2), b = 1. 5090(2), c = 1. 3865 (6)nm, a = 105. 58(1 ), β = 117. 26(2), γ = 66. 812(8)°, V= 2. 464546nm3, Z =4, Dc = 1. 39g· cm-3, u = 11. 6cm-1, F(000) = 1080, R = 0. 051, Rw = 0. 064. The coordination number of Ga is four and the gallium atom is located in a distorted tetrahedron structure.展开更多
