摘要：
The title complex [La(betaine)2(H2O)6Fe(CN)6]?2H2O (betaine = (CH3)3NCH2CO2) has been synthesized and characterized by X-ray single-crystal structure analysis. The crystal crystallizes in monoclinic, space group P21/n with a = 15.793(5), b = 8.927(3), c = 22.257(7) ?, β = 110.147(5)o, C16H38FeLaN8O12, Mr = 729.31, Z = 4, V = 2946.0(15) ?3, Dc = 1.640 g/m3, μ(MoKα) = 1.988 mm-1, F(000) =1476, R = 0.0388 and wR = 0.0827 for 4237 observed reflections (I > 2σ(I)). The La3+ ion is nine-coordinated by one cyano nitrogen atom and eight oxygen atoms of two betaine and six water molecules. Each complex molecule is connected to form a 3D network structure by some O–H…O and O–H…N hydrogen bonds.
