title: Poly[tetrakis(n-propylammonium) [octa-μ-chlorido-dichloridotrinickelate(II)]]: a hybrid organic-inorganic layer compound in the Cs4Mg3F10 structure type.
abstract: The title compound, {(C(3)H(10)N)(4)[Ni(3)Cl(10)]}(n), contains zigzag layers of tri-μ-chlorido-bridged linear 2/m-symmetric Ni(3)Cl(12) segments, linked by mono-μ-chlorido quasi-linear bridges to two other segments at each end. These inorganic layers are interleaved with interdigitated bilayers of mirror-symmetric n-propylammonium cations, the ammonium head groups of which are directed into the inorganic layers to form multiple N-H···Cl hydrogen bonds, while the propyl tail groups pack together in a tongue-and-groove manner in the center of the bilayer. The propyl groups are ordered at 100 K but disordered with opposite conformations on the mirror plane at 240 K.
