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","filename":"X-ray structural investigation on (NH4)3H(SO4)2 single crystal nature of H-bonds.pdf","filesize":[{"value":"1784 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","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.
