Abstract

In the title compound, [MoBr(2)(C(12)H(11)N(2))(C(12)H(10)N(2))(C(5)H(7)O(2))], the Mo(VI) atom is six-coordinated in a distorted octa-hedral geometry by two N atoms from the diphenyl-hydrazide(1-) and diphenyl-hydrazide(2-) ligands, two O atoms from a bidentate acetyl-acetonate ligand and two Br(-) ions. The mol-ecules form an inversion dimer via a pair of weak C-H⋯O hydrogen bonds and a π-π stacking inter-action with a centroid-centroid distance of 3.7401 (12) Å. Weak intra-molecular C-H⋯Br inter-actions and an intra-molecular π-π stacking inter-action with a centroid-centroid distance of 3.8118 (15) Å are also observed.

摘要

在标题化合物[MoBr₂(C₁₂H₁₁N₂)(C₁₂H₁₀N₂)(C₅H₇O₂)]中,Mo(VI)原子由来自二苯基酰肼(1-)和二苯基酰肼(2-)配体的两个N原子、来自双齿乙酰丙酮配体的两个O原子以及两个Br⁻离子以扭曲的八面体几何构型进行六配位。分子通过一对弱的C-H⋯O氢键形成一个反演二聚体,并通过质心-质心距离为3.7401 (12) Å的π-π堆积相互作用。还观察到弱的分子内C-H⋯Br相互作用以及质心-质心距离为3.8118 (15) Å的分子内π-π堆积相互作用。
