Abstract

Single-crystal X-ray studies of a manganese(II) derivative of guanosine 5'-monophosphate, [Mn(5'-GMP)(H(2)O)(5)],3H(2)O, have shown that it is isostructural with its nickel analogue. The manganese atom therefore is bonded to five water molecules with the remaining octahedral co-ordination site being occupied by N-7 of the nucleotide base. No direct metal-phosphate bonding is involved, but there are structure-stabilizing intramolecular hydrogen bonds between two phosphate oxygen atoms and co-ordinated water molecules.

摘要

5'-鸟苷酸锰(II)衍生物[Mn(5'-GMP)(H₂O)₅]·3H₂O的单晶X射线研究表明,它与其镍类似物具有同晶型结构。因此,锰原子与五个水分子键合,核苷酸碱基的N-7占据了八面体配位的其余位点。不涉及直接的金属-磷酸盐键合,但在两个磷酸氧原子和配位水分子之间存在稳定结构的分子内氢键。
