In bis[1-(3-pyridyl)butane-1,3-dionato]copper(II) (the Cu atom occupies a centre of inversion), [Cu(C9H8NO2)2], (I), and bis[1-(4-pyridyl)butane-1,3-dionato]copper(II) methanol solvate, [Cu(C9H8NO2)2].CH3OH, (II), the O,O'-chelating diketonate ligands support square-planar coordination of the metal ions [Cu-O=1.948 (1)-1.965 (1) A]. Weaker Cu...N interactions [2.405 (2)-2.499 (2) A], at both axial sides, occur between symmetry-related bis(1-pyridylbutane-1,3-dionato)copper(II) molecules. This causes their self-organization into two-dimensional square-grid frameworks, with uniform [6.48 A for (I)] or alternating [4.72 and 6.66 A for (II)] interlayer separations. Guest methanol molecules in (II) reside between the distal layers and form weak hydrogen bonds to coordinated O atoms [O...O=3.018 (4) A].
在双[1-(3-吡啶基)丁烷-1,3-二酮基]铜(II)（铜原子占据一个对称中心），即[Cu(C₉H₈NO₂)₂]，(I)，以及双[1-(4-吡啶基)丁烷-1,3-二酮基]铜(II)甲醇溶剂化物，即[Cu(C₉H₈NO₂)₂]·CH₃OH，(II)中，O,O'-螯合二酮酸酯配体支持金属离子的平面正方形配位[Cu - O = 1.948(1)-1.965(1) Å]。在对称相关的双(1-吡啶基丁烷-1,3-二酮基)铜(II)分子的两侧轴向，存在较弱的Cu...N相互作用[2.405(2)-2.499(2) Å]。这导致它们自组装成二维正方形网格框架，其层间间距均匀[对于(I)为6.48 Å]或交替[对于(II)为4.72和6.66 Å]。(II)中的客体甲醇分子位于远端层之间，并与配位的O原子形成弱氢键[O...O = 3.018(4) Å]。
