Single crystals of an organic-inorganic hybrid (C2H5-C6H4-NH2)2ZnBr2 have been grown by the slow-diffusion method and characterized by Single-Crystal X-Ray Diffraction (SC-XRD) at 295 K. This compound crystallizes in the monoclinic system, with the space group C2/c and the following cell parameters: a = 32.336 (3) Å, b = 4.8539 (4) Å, c = 12.2334 (9) Å, β = 97.019 (5)°, V = 1905.7(3) Å3 and Z′ = 4. The crystal packing is based on well-ordered alternating ZnBr2 inorganic layers and C2H5-C6H4-NH2 organic layers. The crystal structure has been analyzed and discussed in terms of molecular geometry as well as intra and intermolecular interactions. Comparisons with some homologues materials of general formula (R-NH2)2ZnX2 (X = Cl, Br), (R = C2H5-C6H4, C6H5) are also done.
