## Abstract

This study reports the crystallographic characterization of a cadmium complex formulated as [Cd(ligand)2I2]·2CH3OH, crystallizing in a space group with Z = 4. The cadmium center resides on a twofold rotation axis and adopts a distorted tetrahedral coordination geometry, bound to two iodide anions and two pyridine nitrogen atoms from the 4-hydroxybenzylidene pyridine-4-carbohydrazide ligands. Bond angles around cadmium range from 94.92° to 124.29°. Intermolecular C–H···I hydrogen-bonding contacts between iodide anions and C–H groups of neighboring complex molecules produce a one-dimensional chain motif. An extensive network of O–H···O, N–H···O, and C–H···O interactions involving both the complex and methanol solvate molecules further extends the packing into a three-dimensional supramolecular architecture.

## Delivery context

The delivery route is not clearly identifiable from this paper. For hydrogen intake, inhalation is the most efficient route; inhalation, however, carries explosion risk (empirical LFL of 10%; high-concentration devices are not recommended).
