| 摘 要： | Two new borate compounds,C4H10N2·B6O8(OH)2 1 and (NH3CH2CH2NH3)B5O8-(OH) 2,have been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction,IR,elemental analysis and thermal analysis. Compound 1 crystallizes in the monoclinic system,space group P21/c,with a=8.3318(17),b=6.2118(12),c=12.479(3) ,β=108.96(3)o,V=610.8(2) 3,Mr=313.02,Z=2,Dc=1.702 g/cm3,μ=0.150 mm-1,F(000)=320,R =0.0387 and wR =0.0924. Its layered structure is linked by infinite covalently coordinated neutral sheets with 3,20-membered window system,which are built up from alternative B6O8(OH)2 subunits donated by two piperzazine nitrogen donors. 2 crystallizes in monoclinic,space group Cc,with a=6.7207(13),b=11.481(2),c=12.564(3) ,β=95.25(3)o,V=965.4(3) 3,Mr=261.18,Z=4,Dc=1.797 g/cm3,μ= 0.164 mm-1,F(000)=536,R=0.0396 and wR=0.0752. Its oxoborate structure is generated from the sheets of 3,9-membered boron rings bonded diamine molecules through electrostatic and H-bonding interactions to form a two-dimensional layered network.

| Abstract: | Two new borate compounds,C4H10N2·B6O8(OH)2 1 and (NH3CH2CH2NH3)B5O8-(OH) 2,have been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction,IR,elemental analysis and thermal analysis. Compound 1 crystallizes in the monoclinic system,space group P21/c,with a=8.3318(17),b=6.2118(12),c=12.479(3) ,β=108.96(3)o,V=610.8(2) 3,Mr=313.02,Z=2,Dc=1.702 g/cm3,μ=0.150 mm-1,F(000)=320,R =0.0387 and wR =0.0924. Its layered structure is linked by infinite covalently coordinated neutral sheets with 3,20-membered window system,which are built up from alternative B6O8(OH)2 subunits donated by two piperzazine nitrogen donors. 2 crystallizes in monoclinic,space group Cc,with a=6.7207(13),b=11.481(2),c=12.564(3) ,β=95.25(3)o,V=965.4(3) 3,Mr=261.18,Z=4,Dc=1.797 g/cm3,μ= 0.164 mm-1,F(000)=536,R=0.0396 and wR=0.0752. Its oxoborate structure is generated from the sheets of 3,9-membered boron rings bonded diamine molecules through electrostatic and H-bonding interactions to form a two-dimensional layered network. |
