The structural data so obtained are compared with other isomorphous crystals reported earlier. Room\r temperature lattice parameters observed are: a= 15.431(3) Å, b = 5.863(4) Å, c = 10.156(2) Å, β = 101.86(3)° and space group is C2/c with Z = 4. Neighbouring sulphate S042 ions are linked together in pairs by a H-bond, O·H···O with Ro-o distance 2.549 A that is slightly larger than the critical H-bond distance showing that the H-bonds are weak. The positions of H-atoms could not be located directly from the structure refinement. However, the Fourier map used to obtain distortion in the electron density distribution around O1 atom shows the H-bond formation. The structural distortion calculated from point charge model using the positional parameters of Sand O atoms reveals that the tetrahedral SO24- is mainly distorted along x-y plane. The statistical disorder or dynamical tunnelling effect in H-atoms could not be identified as the electron density distortion around H-bond is not sufficient to provide double minimum peak."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "(NH4)3H (SO4)2 Zero-dimensional hydrogen-bonded crystal"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "X-ray structural investigation on (NH4)3H(SO4)2 single crystal nature of H-bonds.pdf", "filesize": [{"value": "1784 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1784000.0, "url": {"url": "https://meral.edu.mm/record/2373/files/X-ray structural investigation on (NH4)3H(SO4)2 single crystal nature of H-bonds.pdf"}, "version_id": "a72be7c3-4192-44ca-aa6e-70e9bf50f1c4"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Anamaya"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "T.M.
