Bottom Line: The asymmetric unit of the title compound, (C4H7N2)2[CoCl4], consists of two 2-methyl-imidazolium cations and one tetra-hedral [CoCl4](2-) anion.The anions and cations inter-act through N-H⋯Cl hydrogen bonds to define layers with a stacking direction along [100].Besides van der Waals forces, weak C-H⋯Cl inter-actions between these layers stabilize the crystal packing.

ABSTRACT
The asymmetric unit of the title compound, (C4H7N2)2[CoCl4], consists of two 2-methyl-imidazolium cations and one tetra-hedral [CoCl4](2-) anion. The anions and cations inter-act through N-H⋯Cl hydrogen bonds to define layers with a stacking direction along [100]. Besides van der Waals forces, weak C-H⋯Cl inter-actions between these layers stabilize the crystal packing.

Mentions: The [CoCl4]2− anion is linked via N—H⋯Cl hydrogen bonds to four cations and each cation is linked to two anions (Table 2 ▸). These inter­actions define layers parallel to (100) with alternating [CoCl4]2− anions and cations (Fig. 2 ▸). Within these layers, the 2-methyl­imidazolium cations are involved in π–π stacking inter­actions with a centroid-to-centroid distance of 3.615 (2) Å and a distance between the mean planes of these rings of 3.340 (3) Å. Besides van der Waals forces, weak C—H⋯Cl inter­actions within and between the layers consolidate the crystal packing. The stacking direction of the layers is along [100].
