title: Dinitro-sylbis[tris-(4-methyl-phen-yl)phosphane]iron.
abstract: The title compound, [Fe(NO)(2)(C(21)H(21)P)(2)], belongs to the family of metal dinitrosyl compounds with the general formula Fe(NO)(2)(L)(x), referred to collectively as 'dinitrosyl iron compounds' (DNICs). Herein we report the structure of a dinitrosyl iron diphosphane complex, [Fe(NO)(2)L(2)], with L = P(C(6)H(4)-p-CH(3))(3). There are two crystallographically independent but chemically equal mol-ecules per asymmetric unit. The iron atom in each mol-ecule is tetra-hedrally coordinated by two phosphane ligands and two NO groups, with Fe-N-O angles in the range 173.84 (15)-179.31 (16)°.
