Synthesis and Crystal Structure of [NBu₄]₂[Pt₂₄(CO)₄₈]: An Infinite 1D Stack of {Pt₃(CO)₆} Units Morphologically Resembling a CO‐Insulated Platinum Cable

Abstract

Pieces of eight: Upon crystallization, [NBu4]2[Pt24(CO)48] self-assembles into infinite one-dimensional stacks of {Pt3(CO)6} units arranged in layers separated by [NBu4]+ ions. Close examination of the {Pt3(CO)6} stacks, which resemble CO-insulated platinum cables (see picture; CO ligands omitted), shows them to be composed of alternating blocks of seven {Pt3(CO)6} units and single {Pt3(CO)6} units.
