Kristall panjara nazariyasi
SC: APF = Ο/6 β 52%
Sodda kub (Simple Cubic). Eng kam zich joylashish. Koordinatsion son = 6.
BCC: APF = Οβ3/8 β 68%
Tana markazlangan kub. Koordinatsion son = 8. Misol: Fe (Ξ±), Cr, W.
FCC: APF = Οβ2/6 β 74%
Yuzga markazlangan kub. Koordinatsion son = 12. Eng zich joylashish. Misol: Cu, Al, Au.
NaCl strukturasi
Ikki FCC panjara bir-biriga singdirilgan. NaβΊ va Clβ» navbat bilan. Koordinatsion son = 6.
Olmos strukturasi
Tetraedrik bog'lanish, har atom 4 qo'shni bilan kovalent bog'langan. Juda qattiq.
