Crystal　structure　of　pyridine　and　methanol　axially　coordinated　1,4,8,11,15,18,22,25-octabutyloxyphthalocyaninatocobalt(II)　(viz.　alpha-octabutyloxyphthalocyaninatocobalt)　{[(n-BuO)(8)Pc]　.　Co(Py)(MeOH)}　(1)　was　determined　by　X-ray　diffraction　methods.　Crystal　data:　monoclinic,　space　group　P2(1)/n,　Z　=　4,　a　=　1.06482(4),　b　=　3.5487(2),　c　=　1.79428(9)　nm,　beta　=　103.246(2)degrees,　V　=　6.5792(5)　nm(3),　mu　=　0.325　mm(-1).　The　result　shows　that　the　ring　skeleton　of　1　maintains　planar　conformation,　which　is　similar　to　that　of　unsubstituted　phthalocyanine　but　is　remarkably　different　from　the　saddle　shape,　conformation,　of　1,4,8,11,15,18,22,25-octabutyloxyphthalocyaninatocopper　(11)　{[(n-BUO)(8)PC]Cu}(2),　which　has　no　axial　coordination.　In　the　structure　of　1,　the　substituents;　butyloxy　groups　of　1　somewhat　deviate　from　the　ring　plane,　while　pyridine　and　methanol　are　coordinated　to　the　center　atom　Co　from　opposite　sides　of　the　ring　plane.　In　addition,　all　molecules　are　stacked　along　axis　a　to　form　one-dimensional　molecule　chain,　the　neighboring　molecules　in　the　chain　overlap　to　some　extent　with　a　benzene　ring　and　a　distance　of　0.3565　nm.
