heal.abstractSingle crystals of CaCr(0.84)Fe(3.16)As(3), a Cr substituted analog of CaFe(4)As(3), were grown from Sn flux and characterized with single crystal neutron diffraction. CaCr(0.84)Fe(3.16)As(3) crystallizes in the orthorhombic space group Pnma with a three-dimensional framework, where Fe, Cr, and As form a covalent channel-like network with Ca(2+) cations residing in the channels. CaCr(0.84)Fe(3.16)As(3) has a unit cell of a = 12.057(4) angstrom, b = 3.7374(13) angstrom, and c = 11.694(3) A, as determined by room temperature single crystal neutron diffraction (R(1) = 0.0747, wR(2) = 0.1825). Structural data was also collected at 10 K. The single crystal neutron data showed that Cr selectively occupies a particular metal site, Fe(4). The antiferromagnetic transition associated with spin density wave (SDW) in the parent compound is preserved and shifts from 96 to 103 K with the selective Cr doping. Mossbauer, magnetic, and electrical resistivity measurements are reported.en
