The Ni 3(PO 4) 2·8H 2O crystal crystallizes in the monoclinic system, space group C2/m , with M=128.13, a =0\^994 7(2) nm, b =1.321 7(3) nm; c =0.463 6(1) nm; β=104.80(3)°, V =0.589 3(2) nm 3, Z=2, R=0.027 2 and wR =0.057 5. The network structure consists of vertex sharing which results in the formation of undulating 4 ring chains and 8 ring sheets.展开更多

Single crystal X-ray analysis indicates that this compound crystallizes in a monoclinic system, space group P2 1/n with a=1.438 5(3) nm, b=1.012 2(2) nm, c=1.832 5(4) nm, β=90.21°, V=2\^668 2(9) nm 3, Z=2, D c=2.112 g/cm 3, R=0.055, wR=0.149 7, S=1.037. The structure of 2 6[Co(H 2O) 2(VO) 8(OH) 4(PO 4) 8] is characterized by P-V-O layers constructed by [(VO) 4(OH) 2(PO 4) 4] 6- non-symmetric units. The P-V-O layers are pillared by [Co(H 2O) 2] 2+ group, resulting in the channels within which the protonated diaminoethane and H 3O + are located.展开更多
