Synthesis and Crystal Structure of a Novel Zincophosphite Containing Two-dimensional Inorganic-organic Network

A novel 1,6-hexamethylenediamine-zincophosphite has been synthesized hydrothermally. Its single-crystal structure refinement has shown the zincophosphite with the composition NH+3 (CH2)6 NH+3 [Zn(HPO3)2]2−, Mr= 343.55. It crystallizes in monoclinic, space group C2/c (No. 15). a=2.2391 nm, b=0.8695 nm, c=0.7919 nm, β= 101.062(6)°, V= 1.513 nm3, Dc= 1.508 kg/m3, Z=4, F(000)=712, μ=1.849 mm−1, R1 =0.0416. wR2=O.1023. This phase exhibits infinite inorganic chains of vertex-linked ZnO4 and HPO3. Via the electrostatic attraction, 1.6-hexamethylenediamine cations and inorganic chains construct a novel interesting two-dimensional inorganic-organic network.
