A novel inclusion compound of[Mn(dca)2(3-nic)2]n·(3-nic)2n(1,dca = dicyanamide,3-nic = nicotinamide)has been prepared and characterized by single-crystal X-ray diffraction,elemental analysis and IR.This complex crystallizes in the triclinic system,space group P(1)with a= 7.5979(8),b = 7.7128(9),c = 14.5346(17)(A),α= 100.094(2),β= 92.444(2),γ= 116.736(2)°,V=741.72(15)(A)3,Z = 1,Dc = 1.512 g/cm3,Mr= 675.55,μ = 0.507 mm-1,F(000)= 347,S = 1.023,the final R = 0.0400 and wR = 0.1010.The inclusion compound is constructed by a three-dimensional host network that consists of dca,3-nic and Mn2+with coordination and hydrogen-bonding interactions.In the network,one-dimensional rectangular channels are formed,and the guest molecules(3-nic)are included in the channels.The guest molecules interlink with the host through strong hydrogen bonds.
