Using the hydrothermal method two novel 3D‐coordination complexes [Ln(H 2 O) 3 Re 6 Te 8 (CN) 6 ]· n H 2 O (Ln = La 3+ , Nd 3+ ) have been synthesised and structurally characterised. For compound [La(H 2 O) 3 Re 6 Te 8 (CN) 6 ]·4H 2 O ( 1 ) the unit cell parameters are: Space group P 6 3 / m , a = 9.3060(13), c = 20.528(4) Å, V = 1539.6(4) Å 3 , R f = 0.0597. For compound [Nd(H 2 O) 3 Re 6 Te 8 (CN) 6 ]·H 2 O ( 2 ) the unit cell parameters are: Space group P 6 3 /m, a = 9.3030(10), c = 20.222(4) Å, V = 1515.7(4) Å 3 , R f = 0.0226. The structures of the cluster compounds are topologically analogous to the mononuclear polymeric complex LaCr(CN) 6 ·5H 2 O. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
