我的ms建模 Si6.cif部分輸出是: data_Si6xy _audit_creation_date 2011-09-08 _audit_creation_method 'Materials Studio' _symmetry_space_group_name_H-M 'P1' _symmetry_Int_Tables_number 1 _symmetry_cell_setting triclinic loop_ _symmetry_equiv_pos_as_xyz x,y,z _cell_length_a 15.0000 _cell_length_b 15.0000 _cell_length_c 3.8407 _cell_angle_alpha 90.0000 _cell_angle_beta 90.0000 _cell_angle_gamma 90.0000 loop_ _atom_site_label _atom_site_type_symbol _atom_site_fract_x _atom_site_fract_y _atom_site_fract_z _atom_site_U_iso_or_equiv _atom_site_adp_type _atom_site_occupancy Si1 Si 0.61468 0.50103 0.70324 0.00000 Uiso 1.00 Si2 Si 0.43366 0.37302 0.20332 0.00000 Uiso 1.00 Si3 Si 0.43366 0.62903 0.20332 0.00000 Uiso 1.00 Si4 Si 0.34314 0.50103 0.20332 0.00000 Uiso 1.00 Si5 Si 0.52417 0.37302 0.70324 0.00000 Uiso 1.00 Si6 Si 0.52417 0.62903 0.70324 0.00000 Uiso 1.00 H7 H 0.67395 0.50103 0.37585 0.00000 Uiso 1.00 H8 H 0.67395 0.50103 1.03063 0.00000 Uiso 1.00 H9 H 0.37438 0.28920 0.20334 0.00000 Uiso 1.00 H10 H 0.37438 0.71285 0.20334 0.00000 Uiso 1.00 H11 H 0.28387 0.50103 0.53071 0.00000 Uiso 1.00 H12 H 0.28387 0.50103 -0.12407 0.00000 Uiso 1.00 H13 H 0.58344 0.28920 0.70323 0.00000 Uiso 1.00 H14 H 0.58344 0.71285 0.70323 0.00000 Uiso 1.00 在小木蟲上看了關于abinit 建模的大部分帖子,好像都不太適合我的情況。不知道這種情況下,如何建模???? ????????????? 只要Definition of the unit cell 部分就可以了。 |
