第五章-230种空间群记号

230种晶体学空间群的记号Symbolsofthe230CrystallographicSpaceGroups空间群是点对称操作和平移对称操作的对称要素全部可能的组合。点群表示晶体外形上的对称关系，空间群表示晶体结构内部的原子及离子间的对称关系。空间群一共230个，它们分别属于32个点群。晶体结构的对称性不能超出230个空间群的范围，而其外形的对称性和宏观对称性则不能越出32个点群的范围。属于同一点群的各种晶体可以隶属于若干个空间群230种晶体学空间群的记号Symbolsofthe230CrystallographicSpaceGroups晶系(Crystalsystem)点群(Pointgroup)空间群(Spacegroup)国际符号(HM)圣佛利斯符号(Schfl.)三斜晶系1C1P1CiP单斜晶系2)31(2cP2P21C2m)41(3cPmPcCmCc2/m)61(2hcP2/mP21/mC2/mP2/cP21/CC2/c正交晶系222)91(2DP222P2221P21212P212121C2221C222F222I222I212121mm2)91(2vcPmm2Pmc21Pcc2Pma2Pca21Pnc2Pmn21Pba2Pna21Pnn2Cmm2Cmc21Ccc2Amm2Abm2Ama2Aba2Fmm2Fdd2Imm2Iba2Ima2mmm)281(2hDPmmmPnnnPccmPbanPmmaPnnaPmnaPccaPbamPccnPbcmPnnmPmmnPbcnPbcaPnmaCmcmCmcaCmmmCccmCmmaCccaFmmmFdddImmmIbamIbcaImma四方4P4P41P42P43I4I41晶系PI4/mP4/mP42/mP4/nP42/nI4/mI41/a422P422P4212P4122P41212P4222P42212P4322P43212I422I41224mmP4mmP4bmP42cmP42nmP4ccP4ncP42mcP42bcI4mmI4cmI41mdI41cd2mP2mP2cP21mP21cPm2Pc2Pb2Pn2Im2Ic2I2mI2d4/mmmP4/mmmP4/mccP4/nbmP4/nncP4/mbmP4/mncP4/nmmP4/nccP42/mmcP42/mcmP42/nbcP42/nnmP42/mbcP42/mnmP42/nmcP42/ncmI4/mmmI4/mcmI41/amdI41/acd三方晶系3P3P31P32R3PR32P312P321P3112P3121P3212P3221R323mP3m1P31mP3c1P31cR3mR3cmP1mP1cPm1Pc1RmRc六方晶系6P6P61P65P62P64P63P6/mP6/mP63/m622)61(6DP622P6122P6522P6222P6422P63226mm)41(6vcP6mmP6ccP63cmP63mcm2)41(3hDPm2Pc2P2mP2c6/mmm)41(6hDP6/mmmP6/mccP63/mcmP63/mmc立方晶系23)51(TP23F23I23P213I213m)71(hTPm3Pn3Fm3Fd3Im3Pa3Ia3432)81(OP432P4232F432F4132I432P4332P4132I41323m)61(dTP3mF3mI3mP3nF3cI3dM3m)61(hOPmmPnnPmnPnmFmmFmcFdmFdcImmIad
