title: Bis[(cyanido-κC)bis(1,10-phenanthroline-κ(2)N,N')copper(II)] pentakis-(cyanido-κC)nitro-soferrate(II) dimethyl-formamide monosolvate.
abstract: The title compound, [Cu(CN)(C(12)H(8)N(2))(2)](2)[Fe(CN)(5)(NO)]·C(3)H(7)NO, is formed of discrete [Cu(phen)(2)CN](+) cations (phen is 1,10-phenanthroline), nitro-prusside [Fe(CN)(5)(NO)](2-) anions and dimethyl-formamide (DMF) mol-ecules of crystallization. The metal atom has a distorted trigonal-bipyra-midal coordination environment, defined by four N atoms of two phen mol-ecules and a C atom of the cyanide group (in the equatorial position). The [Fe(CN)(5)(NO)](2-) anion was found to be disordered about (but not on) a crystallographic twofold rotation axis. Geometries were restrained to ideal values. The dimethyl-formamide solvent mol-ecule was found to be disordered about a crystallographic inversion centre.
