Two new coordination polymers differentiated by CH⋯O hydrogen bonding — synthesis and crystal structure of [(oxa)M(DPA)]
摘要:
Two new coordination polymers, [(oxa)Fe(DPA)] (1) (DPA = 2,2-dipyridylamine. oxa = oxalate) and [(oxa)Ni(DPA)] (2). were synthesized through a self-assembly chemical process under hydrothermal conditions, and characterized by single crystal structures. The C-H . . .O hydrogen bonds in 1 and 2 play important roles in the crystal packing of the two new compounds. (C) 2001 Elsevier Science Ltd. All rights reserved.
