Networks. -The title compounds are prepared from the elements (Ta tubes, 1100 K, 48 h) and characterized by powder XRD and magnetic susceptibility measurements. Single crystal XRD data are reported for BaCo2Sn8. Both compounds crystallize with a new structure type in the space group Cccm (Z = 8). The structure of the Ba compound contains CoSn 7 units, which are condensed via common rectangular faces to [Co2Sn10] dimers. The double units form a covalently bonded three-dimensional network through Sn-Co-Sn bridges. BaCo2Sn8 exhibits Pauli paramagnetism. -(SCHWICKERT, C.; POETTGEN*, R.; Z. Naturforsch., B: Chem.

Specific heat, magnetic susceptibility, and neutron scattering have been used to investigate the nature of the spin system in the antiferromagnet NdCoSn. At room temperature NdCoSn has a cubic, Pm-3n structure similar to YbRhSn. Antiferromagnetic interactions between, Nd ions dominate the magnetic character of this sample and at 2.4 K the Nd spins enter a long range order state with a magnetic propagation vector q = (0 0 0) with an ordered moment of 1.78(2) µ at 1.5 K. The magnetic Bragg intensity grows very slowly below 1 K, reaching ~2.4 µ at 350 mK. The average magnetic Nd configuration corresponds to the 3D irreducible representation Γ. This magnetic structure can be viewed as three sublattices of antiferromagnetic spin chains coupled with each other in the 120°-configuration. A well-defined magnetic excitation was measured around the 1 1 1 zone centre and the resulting dispersion curve is appropriate for an antiferromagnet with a gap of 0.20(1) meV.
