title: Ba(14)Cu(2)In(4)N(7), a new subnitride with isolated nitridocuprate groups and indium clusters.
abstract: Single crystals of Ba(14)Cu(2)In(4)N(7), tetradecabarium dicopper tetraindium heptanitride, were synthesized by slow cooling from 1023 K at 7 MPa of N(2) using an Na flux. The compound crystallizes in the monoclinic space group P2/m with Z = 2, and contains 0[CuN(2)] nitridocuprate units and distorted 0[In(4)] clusters. One Ba atom, not connected to any N atoms, is surrounded by 12 other Ba atoms in a barium cuboctahedron. The structural formula is expressed as (Ba)Ba(27)N(6)[CuN(2)](4)[In(4)](2).
