Abstract

It is found that M(AmH)2(3,5-DNB)4·8H2O compounds (where M(II) = Co, Ni; AmH is piperidine PipH = (C5H10NH2)+ or diethylamine DaH = (C4H10NH2)+ cations; 3,5-DNB = (C7H3N2O6)− is the dinitrobenzoic acid anion) are isotypic. The structure of the Ni(PipH)2(3,5-DNB)4·8H2O single crystal is studied. The crystals have a monoclinic system, P21/n space group, Z = 2, a = 6.7694(3) Å, b = 16.0746(6) Å, c = 23.1250(9) Å, β = 97.794(1)°, V = 2493.1(2) Å3, T = 153 K. The final value R(F) = 0.0407 was obtained for 8191 independent reflections with I> 2σ(I). The structural units of the compound studied are as follows: [Ni(OH2)6]2+ complex hexaaquacation, two (PipH)+ cations, four (3,5-DNB)− anions, and two molecules of water of crystallization with the structural formula [Ni(OH2)6](PipH)2(3,5-DNB)4·2H2O. Similar compounds of Ni(II) and Co(II) are isostructural.
