In the title co-crystal, [Mo(C(14)H(9)ClN(2)O(4))O(2)(CH(3)OH)]·C(10)H(8)N(2), the deprotonated Schiff base O,N,O'-chelates to the Mo(VI) atom, the three atoms involved in chelation comprising the fac sites of the octa-hedron surrounding the methanol-coordinated metal atom. The methanol mol-ecule forms an O-H⋯N hydrogen bond to an N atom of the 4,4'-bipyridine solvent mol-ecule; the hy-droxy group of the Schiff base forms an O-H⋯N hydrogen bond to the other N atom of another mol-ecule. The two hydrogen bonds leading to the formation of a helical chain running along the b axis.
在标题共晶体[Mo(C₁₄H₉ClN₂O₄)O₂(CH₃OH)]·C₁₀H₈N₂中，去质子化的席夫碱通过O、N、O'与Mo(VI)原子螯合，参与螯合的三个原子构成围绕甲醇配位金属原子的八面体的面心位置。甲醇分子与4,4'-联吡啶溶剂分子的一个N原子形成O—H⋯N氢键；席夫碱的羟基与另一个分子的另一个N原子形成O—H⋯N氢键。这两个氢键导致形成沿b轴延伸的螺旋链。
