Crystal structural constant of the M(3-aminopridine)2Ni(CN)4 [M = Cu(II) ve Zn(II)] hofmann type complexescalculation from their powder XRD data's.

In this study, the diffraction patterns of Cu-3AP-Ni and Zn-3AP-Ni compounds were indexed with using powder XRD diffraction pattern and crystal system and unit cell parameters with MILLER.FOR, ITO13, TREOR90 computer programmes and Cu-3AP-Ni and Zn-3AP-Ni crystal systems were found as monoclinic with the result of analytical calculation method. Cell parameters were calculated as a=7.9450 Å,b=29.3890 Å,c=4.3805 Å,β=91.6810° for Cu-3AP-Ni and as a=15.4440 Å,b=7.2460 Å,c=7.2530 Å,β=101.9800° for Zn-3AP-Ni. As a result of both ITO13 and TREOR90 computer programmes, crystal systems of both compounds were found to be monoclinic. According to ITO13 programme, cell parameters were calculated as a=16.1830 Å,b=27.6350 Å,c=14.6050 Å,β=91.5620° for Cu-3AP-Ni and as a=15.6949 Å,b=7.2479 Å,c=7.2452 Å,β=102.3292 ° for Zn-3AP-Ni. According to TREOR90 programmes, cell parameters were calculated as a=13.6110 Å,b=10.7980 Å,c=7.6320 Å,β=97.2010°for Cu-3AP-Ni and as a=15.8073 Å,b=7.2408 Å,c=7.2399 Å,β=104.2610° for Zn-3AP-Ni. Cell parameters and indexing process with controlling, alignment of analytic and computer programme data of Cu-3AP-Ni compound were low, alignment of analytic and computer programme of Zn-3AP-Ni were high. These results were indicated that the formation of Cu-3AP-Ni could be found some impurities and structure of Zn-3AP-Ni compound was much more homogeneous and pure. In the calculation of the particle size analysis, for Cu-3AP-Ni compounds the mean particle size was found about 45.8631 nm; for Zn-3AP-Ni compounds was found 38.3929 nm.
