摘　　要：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 P1 with a = 7.5979（8）,b = 7.7128（9）,c = 14.5346（17）,α = 100.094（2）,β = 92.444（2）,γ = 116.736（2）o,V = 741.72（15） 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.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 P1 with a = 7.5979（8）,b = 7.7128（9）,c = 14.5346（17）,α = 100.094（2）,β = 92.444（2）,γ = 116.736（2）o,V = 741.72（15） 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.
