Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te pyridine ka hurihia ki roto i te punaha karaihe orthorhombic me te roopu mokowhiti Pna21 me nga taatai mata a = 1752 pm, b = 897 pm, c = 1135 pm, me nga waeine raupapa 16 mo ia pūtau kotahi (i whangangahia i te 153 K). Hei whakataurite, he orthorhombic hoki te benzene tioata, me te roopu mokowhiti Pbca, a = 729.2 pm, b = 947.1 pm, c = 674.2 pm (i te 78 K), engari ko te maha o nga ngota mo ia pūtau he 4 anake. Ko tenei rereketanga e pa ana ki te waahanga o raro o te ngota pyridine takitahi (C2v vs D6h mo te benzene). He trihydrate (pyridine·3H2O) e mohiotia ana; ka tio hoki i roto i te punaha orthorhombic i roto i te roopu mokowhiti Pbca, nga waahanga whatu a = 1244 pm, b = 1783 pm, c = 679 pm me nga waeine e waru o te raupapa mo ia waahanga waahanga (i whangangahia i te 223 K).  Pātai: E hia ngā wae tātai i ia pūtau kei roto i tētahi trihydrate?
