Tetraaqua­tetrakis­{μ2-[1-(carb­oxylato­meth­yl)cyclo­hex­yl]methanaminium}bis(μ3-hydroxido)bis(nitrato-κ2 O,O′)tetrazinc(II)

By Elise J. C. de Vries, Caryn Gamble and Ahmed Shaikjee


As the title gabapentin complex, [Zn4(OH)2(NO3)2(C9H17NO2)4(H2O)4](NO3)4 is located about a centre of inversion, the asymmetric unit contains two disordered nitrate ions and half a complex mol­ecule. The two zinc ions have different coordination environments: one is slightly distorted octa­hedral and the other is trigonal–pyramidal. The conformation of the gabapentin mol­ecule is defined by the formation of two intra­molecular O—H⋯O hydrogen bonds. Furthermore, the ammonium H atoms are involved in numerous hydrogen bonds with the disordered nitrate anions
